Sulfur trioxide is formed in the reaction shown below. $2\text{SO}_2(g) + \text{O}_2(g) \rightleftharpoons 2\text{SO}_3(g) \qquad \Delta H = -195\ \text{kJ}$ Which change in conditions would result in a larger amount of $\text{SO}_3$ at equilibrium?
- Aadding a catalyst
- Bincreasing the pressure
- Cincreasing the temperature
- Dremoving some $\text{SO}_2$ and $\text{O}_2$
