7.10 Reaction Quotient and Le Châtelier’s Principle
7.9 Introduction to Le Châtelier’s Principle
A rigid, sealed \(1.0 \text{ L}\) container holds an equilibrium mixture of \(\text{N}_2\text{O}_4\text{(g)}\) and \(\text{NO}_2\text{(g)}\) at a constant temperature, as represented by the following equation.
\[\text{N}_2\text{O}_4\text{(g)} \rightleftharpoons 2\,\text{NO}_2\text{(g)}\]
A sample of \(\text{Ar(g)}\) is injected into the container at the same temperature. Which of the following best predicts and explains the effect of adding \(\text{Ar(g)}\) on the equilibrium system?
\[\text{N}_2\text{O}_4\text{(g)} \rightleftharpoons 2\,\text{NO}_2\text{(g)}\]
