Given the equilibria:

determine the equilibrium expression for the sum of the two reactions.

Strategy 

Write the equilibrium expressions for the two reactions. Multiply them to obtain the equilibrium expression for the sum of the two reactions. Check your answer by adding the two reactions and comparing the sum to the equilibrium expression you determined.
