Which of the following will change the value of the equilibrium constant for the reaction? \( N_{2}(g)+O_{2}(g) \leftrightharpoons 2 N O(g) \)

1. Add more \( N_{2} \)
2. Increase of pressure
3. Use a smaller reaction vessel
4. Increase the temperature

Correct answer: Increase the temperature

Solution

The equilibrium constant is only affected by temperature changes because it is related to the reaction's enthalpy and Gibbs free energy.
