Unformatted text preview: In this case, the entropy of the mixed gas is greater than either pure gas S equilbrium > S NO2 or S N2O4 The Law of Mass Action—gives a general description of the equilbriu condition j A + k B ( ) l C m D [C] l [D] m = Q [A] j [B] k Q = reaction quotient of reactants/products At equilubrium, Q = K equilibrium constant a true constant its value at a given T does not depend on the initial concentration of reactants & products K will always vary with T Q = K equilibrium Q > K reaction shifts left Q < K reaction shifts right We noted earlier that at equilibrium ,we reach a minimum on the free energy curve There must be some relationship between the equilibrium constant and the standard free 10/15/09 energy of reaction...
