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...
