Question

Consider the reaction and the associated equilibrium constant. Determine the equilibrium concentrations of A and B. Assume the initial concentration of A = 1.0 M and that no B is present at the beginning of the reaction, since B is the product.

                                                A(g)    ⇌  B(g)              K_c = 4.0

Group of answer choices

A [A] = 0.2 M; [B] = 0.8 M

B [A] = 0.4 M; [B] = 0.1 M

C [A] = 1. M; [B] = 4. M

D [A] = 0.5 M; [B] = 0.5 M
