Ch. 16 In-Class Problem

Consider the ammonia synthesis reaction

N2(g) + 3 H2(g) → 2 NH3(g) ΔG° = -33.3 kJ/mol

For each of the following mixtures of reactants and products at 25°C predict the

direction in which the system will shift to reach equilibrium.

a. [NH3] = 1.00 M; [N2] = 1.47 M; [H2] = 1.00 x 10-2 M

b. [NH3] = 1.00 M; [N2] = 1.00 M; [H2] = 1.00 M
