Consider the following reaction: CO₂(g) + C(graphite) ⇌ 2CO(g)
A reaction mixture initially contains 0.56 bar CO₂ and 0.32 bar CO. Determine the equilibrium pressure of CO if K_p for the reaction at this temperature is 2.25 bar.

Question

Quizplus · Accepted Answer

To find the equilibrium pressure of CO, use the expression for Kp: Kp = (P_CO)^2 / P_CO2. Let x be the change in pressure of CO2 and CO at equilibrium. Then, P_CO2 = 0.56 - x and P_CO = 0.32 + 2x. Substitute these into the Kp expression and solve for x. The equilibrium pressure of CO is 0.32 + 2x, which calculates to approximately 0.83 bar.
