Question
**Equilibrium Shifts in Chemical Reactions**

For each of the following changes at equilibrium, indicate whether the equilibrium shifts in the direction of the products, the reactants, or does not change.

**Reaction:**
\[ \text{N}_2 (g) + \text{O}_2 (g) + \text{heat} \rightleftharpoons 2\text{NO} (g) \]

**Changes:**
a. Increasing the temperature –  
b. Decreasing the volume of the container –  
c. Adding a catalyst –  
d. Adding more \(\text{N}_2 (g)\) –  

**Explanation:**
The reaction is given as a reversible reaction where nitrogen gas (\(\text{N}_2\)) and oxygen gas (\(\text{O}_2\)) combine with heat to form nitrogen monoxide (\(\text{NO}\)). Changes in temperature, pressure, and concentration can affect which direction the equilibrium shifts according to Le Chatelier’s Principle. This principle helps predict the response of an equilibrium system to external changes.
