### Chapter 16: Equilibrium Processes

#### Be sure to answer all parts.

Consider the following equilibrium process at 686°C:

\[ \text{CO}_2 (g) + \text{H}_2 (g) \leftrightharpoons \text{CO} (g) + \text{H}_2\text{O} (g) \]

The equilibrium concentrations of the reacting species are:

\[ \left[ \text{CO} \right] = 0.0500 \, M, \quad \left[ \text{H}_2 \right] = 0.0420 \, M, \quad \left[ \text{CO}_2 \right] = 0.0900 \, M, \quad \left[ \text{H}_2\text{O} \right] = 0.0350 \, M \]

**(a) Calculate \( K_c \) for the reaction at 686°C.**

\[ \boxed{} \]

**(b) If we add \(\text{CO}_2\) to increase its concentration to \(0.480 \, \text{mol/L}\), what will the concentrations of all the gases be when equilibrium is reestablished?**

**CO\(_2\):**

\[ \boxed{\text{ } M} \]

**H\(_2\):**

\[ \boxed{\text{ } M} \]

**CO:**

\[ \boxed{\text{ } M} \]

**H\(_2\)O:**

\[ \boxed{\text{ } M} \]
