Quizplus · Accepted Answer

The equilibrium constant K is given by the ratio of the partial pressures of the products to the partial pressures of the reactants at equilibrium. At equilibrium, the partial pressures of the products are P_N2=0.4 atm and P_H2O=0.4 atm, and the partial pressures of the reactants are P_NO=0.3 atm and P_H2=0.4 atm. Therefore, K = (P_N2P_H2O)/(P_NOP_H2) = (0.4*0.4)/(0.3*0.4) = 28.0.
