The rate of diffusion through a semipermeable membrane is slowest when ____.
A)molecules are small
B)there is a concentration gradient
C)there is a difference in charge
D)there is high pressure
E)temperatures are low

Question

Quizplus · Accepted Answer

Diffusion occurs faster at higher temperatures as the kinetic energy of molecules increases, allowing them to move more rapidly. Therefore, when temperatures are low, the rate of diffusion through a semi-permeable membrane is slowest.

The Rate of Diffusion Through a Semipermeable Membrane Is Slowest
