B)Diffusion of K+ from A to B will be equal to the diffusion of K+ from B to A
C)There will be a potential difference across the membrane,with side A negative relative to side B
D)The electrical and diffusion potentials for K+ will be equal in magnitude and opposite in direction
E)All of the choices are correct

At equilibrium, the concentration of K+ in A will be lower than it was at time zero (A). Diffusion of K+ from A to B will be equal to the diffusion of K+ from B to A (B). There will be a potential difference across the membrane, with side A negative relative to side B (C). The electrical and diffusion potentials for K+ will be equal in magnitude and opposite in direction (D).
