When the system is at equilibrium at 200°C, the concentrations are found to be: [A] = 0.20 M, [B] = 0.30 M, [C] = 0.30 M. If the volume of the container is suddenly doubled at 200°C, what will be the new equilibrium concentration of C?

Given:
A(g) B(g) + C(g)

When the system is at equilibrium at 200°C, the concentrations are found to be: [A] = 0.20 M, [B] = 0.30 M, [C] = 0.30 M. If the volume of the container is suddenly doubled at 200°C, what will be the new equilibrium concentration of C?



a. 0.060 M
b. 0.18 M
c. 0.24 M
d. 0.29 M
e. 0.35 M


Answer: b. 0.18 M
