1 (120). For the reaction SO 3 (g) + H 2 O(g) = H 2 SO 4 (g) calculate the equilibrium constant at T and P given below. Assume that both the reactants and the products are ideal gases. Their thermodynamic properties at T = 298 K and P =1 bar are listed in the table below. [Note: the above reaction is responsible for what is commonly called “acid rain”].
