AP Chemistry
7.9 Introduction to Le Châtelier’s Principle
7.1 Introduction to Equilibrium
At a particular temperature, the reaction
\(2\text{SO}_2\text{(g)}+\text{O}_2\text{(g)}\rightleftharpoons2\text{SO}_3\text{(g)}\)
is at equilibrium in a sealed, rigid vessel. A small amount of solid \(\text{V}_2\text{O}_5\), which acts as a catalyst and has negligible volume, is added while the temperature remains constant. Which choice correctly predicts both the forward and reverse reaction rates immediately after the catalyst is added and the partial pressure of \(\text{SO}_3\text{(g)}\) after sufficient time?
