# The synthesis of ammonia gas is represented by the following equation:

\[\text{N}_2\text{(g)} + 3\,\text{H}_2\text{(g)} \rightleftharpoons 2\,\text{NH}_3\text{(g)} \quad \Delta H^\circ = -92.2\text{ kJ/mol}_{\text{rxn}}\]

A mixture of \(\text{N}_2\text{(g)}\), \(\text{H}_2\text{(g)}\), and \(\text{NH}_3\text{(g)}\) is initially at equilibrium in a cylinder fitted with a movable piston at \(450\text{ K}\). The temperature of the system is increased to \(550\text{ K}\). Which of the following correctly predicts the effect of the temperature increase on the value of the equilibrium constant, \(K_p\), and identifies a change in container volume that will shift the equilibrium position toward the products?

Which of the following correctly predicts the effect of the temperature increase on the value of the equilibrium constant, \(K_p\), and identifies a change in container volume that will shift the equilibrium position toward the products?

- **A.** The value of \(K_p\) increases, and the volume of the container should be decreased.
- **B.** The value of \(K_p\) decreases, and the volume of the container should be decreased.
- **C.** The value of \(K_p\) increases, and the volume of the container should be increased.
- **D.** The value of \(K_p\) decreases, and the volume of the container should be increased.
