7.10 Reaction Quotient and Le Châtelier’s Principle
7.9 Introduction to Le Châtelier’s Principle
A rigid, sealed vessel contains an equilibrium mixture of \(\text{N}_2\text{O}_4(g)\) and \(\text{NO}_2(g)\) at \(298 \, \text{K}\) according to the reaction represented below.
\[ \text{N}_2\text{O}_4(g) \rightleftharpoons 2\,\text{NO}_2(g) \qquad \Delta H^\circ_{\text{rxn}} = +57.2 \, \text{kJ/mol}_{\text{rxn}} \]
The temperature of the vessel is increased from \(298 \, \text{K}\) to \(350 \, \text{K}\). Which of the following correctly predicts and explains the change in the equilibrium partial pressure of \(\text{NO}_2(g)\) after equilibrium is re-established?
