Question

question 51 (1.7 points) saved 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.

Explanation:

Net - diffusion rate is directly proportional to the concentration gradient. Higher molecular weight substances diffuse more slowly. Also, higher temperature generally increases the diffusion rate as it provides more kinetic energy to the molecules.

Answer:

D. The greater the concentration gradient, the faster the rate.
