Problem

Suppose the exothermic reaction

2 SO(g) + O(g) ⇌ 2 SO(g)

comes to equilibrium. Then we increase the temperature and decrease the total pressure simultaneously. What will be the effect on the net amount of SO3(g)?

1. It decreases.

2. It does not change.

3. It increases.

4. It may either increase, decrease, or remain the same, depending on the numerical value of the equilibrium constant.

5. It may either increase, decrease, or remain the same, depending on the sizes of the temperature and pressure changes.
