Determine the value of the equilibrium constant for each reaction from the equilibrium concentrations given. (Concentrations are in mol/L.) (Hint: See
Sample Problem A.)
a. A + B → C; [A] = 2.0; [B] = 3.0; [C] = 4.0
b. D + 2E → F + 3G; [D] = 1.5; [E] = 2.0;
［F］ = 1.8；［G］ =1.2
c. N2(8) + 3H, (g) → 2NH (g); [N,] = 0.45;
[H2] = 0.14; [NH3 = 0.62
