1) Consider the generalized reaction below, What are the equilibrium concentrations of all substances?

Reaction conditions: 1.25L container, 1.0atm, 25oC

A2 (g) + BC (s) ? AC (g) + AB (g),     Kc = 1.19×10−6

Starting conditions: 

A2 = 0.109 mol

BC = 0.085 mol

no products

2.Consider the generalized reaction from the previous question, repeated below.

A2 (g) + BC (s) ? AC (g) + AB (g),     Kc = 1.19×10-6 , T = 25.0oC

What do you predict the sign for ΔS°rxn to be? Calculate ΔG°rxn. Based on your answer for parts 1 and 2, is this reaction endothermic or exothermic? Explain your reasoning.
