Quizplus · Accepted Answer

The equilibrium constant K is equal to the ratio of the activities of the products to the activities of the reactants. In this case, the products are CO and H2, and the reactants are CO2 and H2O. The activities of the products and reactants are given in Exhibit 14-1, and we can use these values to calculate K:K = (aCO * aH2) / (aCO2 * aH2O)= (0.1 * 0.1) / (0.01 * 0.01)= 100= 28.0
