Which of the following factors influences the rate at which diffusion takes place?
Many factors influence the rate at which diffusion takes place including the medium through with a substance is diffusing the size of molecules diffusing the temperature of the materials and the distance molecules travel between collisions.
What factors influence the rate of diffusion across a membrane?
Concentration gradient size of the particles that are diffusing and temperature of the system affect the rate of diffusion. Some materials diffuse readily through the membrane but others require specialized proteins such as channels and transporters to carry them into or out of the cell.
What factors affect the rate of osmosis?

What factors affect the diffusion rate in solid metal crystals?
- Diffusion mechanism
- Temperature of diffusion
- Concentration of the diffusion species (concentration gradient)
- Type of crystal structure (bcc > fcc)
- Type of crystal imperfections.
Which of the following factors does not have a direct influence on the rate of diffusion?
The factor that does not affect the rate of diffusion are the electrical charges of the diffusion particles. The electrical charges do not participate in such processes.
What are 2 variables that affect the rate of diffusion?
Two variables that affect the rate of diffusion are the size or molecular weight of the molecule that is diffusing across the membrane and the concentration gradient itself.
Which one or more physical factors affect the rate of diffusion quizlet?
The higher the temperature the higher the kinetic energy of particles. As temperature increases rate of diffusion will increase. The greater the difference in concentration on either side of the membrane the greater the rate of diffusion.
Does polarity affect the rate of diffusion?
Polarity does affect diffusion but only in the case where diffusion is occurring across the cell membrane.
Which of the following factors most influence the rate of molecular movement into cells?
Temperature: The higher the temperature the faster molecules move. So as temperature increases the rate of diffusion increases. Size of molecule: Smaller molecules tend to travel further before colliding with other molecules so diffusion rates are faster for smaller molecules.
Which factors will affect the rate of diffusion of a gas select all that apply?
- Membrane thickness – the thinner the membrane the faster the rate of diffusion. …
- Membrane surface area – the larger the surface area the faster the rate of diffusion. …
- Pressure difference across the membrane.
- Diffusion coefficient of the gas.
What are the main factors which affect the speed of acceptance of an innovation?
There are certain product and service characteristics that affect the diffusion process and can influence consumer acceptance of new products and services the five factors that can impact the diffusion process and the rate of adoption are relative advantage compatibility complexity trialability and observability.
What environmental factors affect kinetic energy and diffusion?
What environmental factors affect kinetic energy and diffusion? Temperature pressure nature of the material size of the molecule.
What affect the rate of facilitated diffusion?
The main factors affecting the process of facilitated diffusion are: Temperature– As the temperature increases the movement of the molecules increases due to an increase in energy. Concentration- The movement of the molecules takes place from the region of higher concentration to lower concentration.
How surface area affects the rate of diffusion?
Explanation: When the cell increases in size the volume increases faster than the surface area because volume is cubed where surface area is squared. When there is more volume and less surface area diffusion takes longer and is less effective. … this is actually why cells divide.
What factors affect the rate of osmotic movement of water?
The rate of osmosis varies with a number of factors including temperature pressure and the difference in solute concentrations between two solutions separated by a selectively permeable membrane.
What three factors affect the diffusion of water through a membrane by osmosis?
Osmosis is the diffusion of water through a selectively permeable membrane from a higher concentration to a lower concentration. Several factors can affect the rate of osmosis. For example temperature particle size and the size of the concentration gradient can all affect the rate of osmosis.
What factors determine the rate and direction of osmosis quizlet?
the concentration of water determines the direction in which molecules will move during osmosis. the point at which water molecules enter and leave a cell at the same rate. the concentration inside and outside of the cell are equal.
What are the factors affecting the rate of diffusion Class 9 Chemistry?
Rate of diffusion is affected by concentration gradient membrane permeability temperature and pressure. Diffusion takes place as long as there is a difference between the concentrations of a substance across a barrier.
What are the factors on which the direction of diffusion of gases depends Class 10?
Answer Expert Verified. Concentration and pressure are 2 factors which decide the direction of diffusion and oxygen and carbon dioxide.
What are the factors affecting diffusion Class 9?
What are the factors affecting diffusion rate in metals?
3. Factors Effecting Diffusion of Metals: The diffusion coefficient D is normally not a constant but is a (strong) function of temperature concentration and crystal structure.
Does pH affect the rate of diffusion?
In general a decrease in diffusion coefficient was observed with increasing pH.
How does pressure affect the rate of diffusion?
As with any chemical reaction increasing the temperature or pressure increases the kinetic energy of the particles thus increasing the rate of diffusion.
Which of the following transport is not highly selective?
Simple Diffusion It is a physical phenomenon which involves the movement of water fromhigher concentration to lower concentration. It is not a selective process and do not requireenergy.
Why does increasing the pressure increase the filtration rate?
The increase in pore size increased the filtration rate because more filtrate was allowed to go through the membrane. … Pressure increased the filtration rate but not the concentration of solutes because it increased the hydrostatic pressure gradient that exists.
Which pair of factors is inversely proportional to the rate of diffusion?
It states that ‘the rate of diffusion is proportional to both the surface area and concentration difference and is inversely proportional to the thickness of the membrane‘.
What factors affect the rate of diffusion and how?
The greater the difference in concentration the quicker the rate of diffusion. The higher the temperature the more kinetic energy the particles will have so they will move and mix more quickly. The greater the surface area the faster the rate of diffusion.
What factors decrease the rate of diffusion quizlet?
The closer the distribution of the material get to equilibrium the slower the rate of diffusion becomes. Higher temperature increase the energy and therefore the movement of the molecules increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules thus decreasing the rate of diffusion.
