Question

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 the equilibrium pressure of the reaction mixture in terms of the above parameters. (b.) How would the use of a smaller reactor affect the conversion of A2? (c) How would the presence of an inert gas in the reactor affect the conversion of A2? (d) How would a temperature increase affect the conversion of A2 if the reaction is endothermic? (e) How would a catalyst affect the conversion of A2? () How would the use of A2 and B2 in a stoichiometric (2:1) prop2rtion affect the conversion of A2?
