7.10 Reaction Quotient and Le Châtelier’s Principle
7.9 Introduction to Le Châtelier’s Principle
A gaseous reaction mixture is allowed to reach equilibrium in a rigid, closed container of fixed volume at a constant temperature \(T\), according to the following equation:
\[ 2\text{SO}_2\text{(g)} + \text{O}_2\text{(g)} \rightleftharpoons 2\text{SO}_3\text{(g)} \]
A sample of \(0.10\text{ mol}\) of \(\text{Ar(g)}\) is injected into the container at constant temperature. Which of the following correctly predicts and explains the effect of adding \(\text{Ar(g)}\) on the equilibrium position of the system?
