Using Le Chatelier's Principle, What will happen to the number of moles of SO3 in equilibrium with SO2 and O2 in the reaction? 2SO3(g) ⇌ 2SO2(g) + O2(g) in each of the following cases:

1. Oxygen is added to reaction container.

2. The pressure is increased by decreasing the volume of the reaction container.

3. In the rigid container (i.e. constant volume), the pressure is increased by adding argon gas.

4. The temperature of the reaction container is decreased (Note: decomposition reaction is endothermic).

5. Gaseous sulfur dioxide is removed from reaction container.
