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?
a. Oxygen gas is added
b. The pressure is increased by decreasing the volume of the reaction container
c. In a rigid reaction container, the pressure is increased by adding argon gas
d. The temperature is decreased (the reaction is endothermic)
e. Gaseous sulfur dioxide is removed
