A simplified form of the Fick diffusion equation is J = KA (C1-C2) where J is the rate of diffusion, K is a constant, A is the area across which diffusion is occurring, and C1 and C2 are the concentrations of the substance on either side of the membrane. Given this, which of the following would INCREASE the rate of diffusion of a solute?
A. A decrease in D
B. A decrease in A
C. An equivalent decrease in both C1 and C2
D. An equivalent increase in both C1 and C2
E. An increase in C1 while holding C2 constant
Answer: E
