Solution: What is the expression for Kp for the reaction below?4 CuO(s) + CH4(g) ⇌ CO2(g) + 4 Cu(s) + 2 H2O(g)

Problem

What is the expression for Kp for the reaction below?

4 CuO(s) + CH4(g) ⇌ CO2(g) + 4 Cu(s) + 2 H2O(g)

Solution

We're being asked to write the expression for the equilibrium constant Kp for the following reaction:

4 CuO(s) + CH4(g) ⇌ CO2(g) + 4 Cu(s) + 2 H2O(g)


Since the reaction is balanced, we can proceed to write the Kp expression. Recall that the equilibrium constant is the ratio of the products and reactants
