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

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 for CO2 and CO. At equilibrium, 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 atm.
