Question

4. Given the reaction: 3X(g) + Y(g) ↔ 2 Z(g) + W(g)
Which of the following is true?
a. Kc > Kp
b. Kc < Kp
c. Kc = Kp
5. For the reaction: 2 X(s) + 3 Y(g) ↔ 2 Z(s) Kc = ???
At equilibrium, the system contains [Y] = 0.0025 M. The amounts of [X(s)] = 100 mol/L
and [Z(s)] = 395 mol/L. What is the value of the equilibrium constant?
6. For the reaction: 3A(g) + 2B(g) ↔ 3 C(g) Kc = 0.0245
At equilibrium, the system contains [A] = 0.075 M and [B] = 0.115 M. What is the
concentration of C at equilibrium (in M)?
7. Given the reaction A(g) + 3B(g) ↔ 2 C(g) Kc = ???
Initially, only 0.200 M of C(g) is present. At equilibrium, 0.050 M of A is present. What is
the value of the equilibrium constant?
