**Equilibrium and Reaction Shift Analysis**

**Problem Statement:**

Consider the chemical equilibrium below and predict the direction that the equilibrium will shift for each of the following changes:

\[ \text{C (s) + H}_2\text{O (g) + heat} \rightleftharpoons \text{CO (g) + H}_2\text{ (g)} \]

**Changes to Consider:**

a) Cooling

b) Removing CO (g)

c) Adding H\(_2\) (g)

d) Adding H\(_2\)O (g)

**Explanation:**

- **Cooling:** Decreases the temperature. In an endothermic reaction (heat is a reactant), cooling shifts the equilibrium to the left to generate more heat.
- **Removing CO (g):** Reduces product concentration. The equilibrium shifts to the right to increase CO.
- **Adding H\(_2\) (g):** Increases product concentration. The equilibrium shifts to the left to reduce H\(_2\).
- **Adding H\(_2\)O (g):** Increases reactant concentration. The equilibrium shifts to the right to consume H\(_2\)O. 

This analysis uses Le Châtelier's principle to predict the direction of the equilibrium shift for each perturbation.
