Question

What are the factors affecting the rate of diffusion?

Answer 1

These are the factors that affect rate of Diffusion;

The size of the molecule: The smaller the molecule such as gas, the faster the rate of diffusion while the larger the molecules (liquid) the slower the rate of diffusion

Concentration gradient: The greater the concentration difference, the faster the rate of diffusion.

Temperature: The higher the temperature, the faster the rate of diffusion

State of matter: Diffusion in gas molecules is faster than the diffusion in liquids.

Answer 2

Answer:

• Diffusion is the passive movement of substances from a region of higher concentration to a region of lower concentration.
• Diffusion of substances plays an important role in cellular transport in plants.
• 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.
• However, diffusion stops, when the concentrations of the substance on either side of the barrier become equal.
• The permeability of a membrane affects the rate of diffusion.
• Diffusion rate increases as membrane permeability increases.
• Changes in temperature and pressure values also affect the diffusion of substances.

• Pressure plays an important role in the diffusion of gases as gases diffuse from a region of higher partial pressure to a region of lower partial pressure.
