For the gaseous equilibrium represented below, it is observed that greater amounts of PCl3 and Cl2 are produced as the temperature is increased.

Question

PCl5(g) <===> PCl3(g) + Cl2(g)
a) What is the sign of S° for the reaction? Explain.
b) What change, if any, will occur in G° for the reaction as the temperature is increased. Explain your reasoning in terms of thermodynamic principles.
c) If He gas is added to the original reaction mixture at constant volume and temperature, what will happen to the partial pressure of Cl2? Explain.
d) If the volume of the original reaction is decreased at constant temperature to half the original volume, what will happen to the number of moles of Cl2 in the reaction vessel? Explain.
