Question

Which of these factors affect the rate of diffusion?

• A. Concentration of molecules
• B. Molecular weight
• C. Temperature
• D. All of the above

Answer 1

The correct option is D All of the above

Diffusion is the net movement of molecules or atoms from a region of high concentration (or high chemical potential) to a region of low concentration. Molecular weight, temperature, the concentration of molecules and diffusion distance affect the rate of diffusion.
