7.9 Introduction to Le Châtelier’s Principle
7.1 Introduction to Equilibrium
A mixture of \(\text{SO}_2\text{(g)}\) and \(\text{O}_2\text{(g)}\) is introduced into a rigid \(1.0\text{ L}\) container at \(700\text{ K}\) and allowed to react according to the equation below.
\[ 2\,\text{SO}_2\text{(g)} + \text{O}_2\text{(g)} \rightleftharpoons 2\,\text{SO}_3\text{(g)} \]
In Trial 1, the reaction proceeds to dynamic equilibrium in the absence of a catalyst. In Trial 2, the exact same initial amounts of reactants are reacted at \(700\text{ K}\) in an identical container in the presence of a solid \(\text{V}_2\text{O}_5\) catalyst. Which of the following statements best compares the final equilibrium state in Trial 2 to that in Trial 1, and provides the correct justification?
