Question

Is the diffusion rate dependent on size?

Answer 1

Diffusion:

1. Diffusion is defined as the movement of molecules from a higher concentration to a lower concentration.
2. It occurs due to the random movement of molecules.
3. It is dependent on factors such as concentration gradient, temperature, size of molecules, surface area of the membrane, etc.

Effect of size of molecules on diffusion:

1. The rate of diffusion is inversely proportional to the size of the molecules.
2. This means that the smaller is the size of the molecule, the higher is the rate of diffusion.
