Which of the following statements is correct regarding net diffusion?
A) Molecular weight of a substance does not affect the rate.
B) The lower the temperature, the faster the rate.
C) The rate is independent of temperature.
D) The greater the concentration gradient, the faster the rate.

Question

Quizplus · Accepted Answer

Net diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. The greater the concentration gradient (the difference in concentration between the two areas), the faster the rate of diffusion. Molecular weight does affect the rate, as larger molecules diffuse more slowly. Temperature also affects the rate, with higher temperatures leading to faster diffusion due to increased molecular motion. Therefore, option D is correct.
