The equilibrium constant, K, of a reaction at a particular temperature is determined by the concentrations or pressures of the reactants and products at equilibrium. For a gaseous reaction with the general form aA+bB⇌cC+dD the Kc and Kp expressions are given by Kc=[C]c[D]d[A]a[B]b Kp=(PC)c(PD)d(PA)a(PB)b The subscript c or p indicates whether K is expressed in terms of concentrations or pressures. Equilibrium-constant expressions do not include a term for any pure solids or liquids that may be involved since their composition...

Problem 7 The gas-phase reaction, 2A2 + B2 2A2B, is carried out in a constant- volume reactor (volume V) at temperature T. No g-moles each of A2 and B2 are charged to the reactor, which is evacuated initially, and the reaction proceeds to equilibrium. The equilibrium constant Ka of the reaction-which is based on the pure-component standard state of 1 atm and temperature T-is known. The reaction mixture behaves as an ideal-gas mixture. (a) Express the conversion of A2 and...
