Here are the answers to Review Homework for Equilibrium - Revised 2018.

1a) K = [NH3 (g)]E2
            [H2 (g)]E3 [N2 (g)]E1


1b) K = 157 M--2

1ci) Shift Equilibrium RIGHT

1cii) Shift Equilibrium to the LEFT

1d) MORE PRODUCT


2) No (remember Equilibrium is when the Rate of Forward Reaction = Rate of Backward Reaction

3) Dynamic Equilibrium include definition above and that even though the concentration of all the species at equilibrium is constant over time does not mean that the reactions stopped. Both reactions are going constantly as one set of products are made, another product set is reacted back to reactants thereby having no net change.

4) At Equilibrium the Gibbs Free Energy difference between the reactants and products is "zero". In this way, every time Gibbs Free Energy is released by a set of reactants becoming products, that exact energy is used so that a set of products can become a set of reactants. So that is the energy basis for why equilibrium is the condition when the rate of the forward reaction = rate of the backward reaction.
