Question
1. The equilibrium constant is given for two of the reactions below. Determine the value of the missing equilibrium constant.
2A(g) + B(g) ? A2B(g) Kc = ?
A2B(g) + B(g) ? A2B2(g) Kc = 16.4
2A(g) + 2B(g) ? A2B2(g) Kc = 28.2
11.8
2. Consider the following generic reaction for which K = 2.54.
3 Z + Q ? 2 X
What is the value of K for the following reaction
4 X ? 6 Z + 2 Q
0.197
3. For the reactionA(g)?2B(g) , a reaction vessel initially contains only A at a pressure of PA =1.00atm . At equilibrium, PA =0.21atm . Calculate the value of Kp . (Assume no changes in volume or temperature.)

Explanation / Answer
multiply the equilibrium expression for the first reaction by the second one
[AB] / [A] [B] * [A2B] / [AB] [A] = [A2B] / [A]^2 [B] = 16.4*28.2=answer
