Consider the following equilibrium for which ?H 0
2SO2(g) + O2(g) ↔ 2 SO3(g)
How will each of the following changes affect an equilibrium mixture of the three gases:
(a) O2(g) is added to the system;
(b) the reaction mixture is heated;
(c) the volume of the reaction vessel is doubled;
(d) a catalyst is added to the mixture;
(e) the total pressure of the system is increased by adding a noble gas;
(f) SO3(g) is removed from the system?
