Question

It is possible to predict the equilibrium constant of a reaction by combining two or more reactions for which the value of K is known. When combining equilibrium constants, it is important to note the following: When reactions are added, their K values are multiplied. When a reaction is reversed, its K value is inverted; that is Krevese = 1/Kforward. When the coefficients of a reaction are multiplied by a factor, the K value is raised to the power of that factor. Determine the equilibrium constant, Kgoal, for the reaction Determine the value of the equilibrium constant, Kgoal, for the reaction N2(g) + 02(g) + H2(g) 1/2N2H4(g) + NO2(g) , Kgoal = ? by making use of the following information: N2(g) + O2(g) 2NO(g), K1 = 4.10 times 10-31 N2(g) + 2H2(g) N2H4(g) K2 = 7.40 times 10-26 2NO(g) + O2(g) 2NO2(g), K3 = 6.00 times 10-13

Explanation / Answer

Kgoal =K1 x K2 x K3 = 1.8204 x 10^(-68)
