A undergoes a reversible reaction, AB, over a catalyst. A and B are liquids and of identical density. The equilibrium constant for the reaction is 5.8. For a packed bed reactor, pure A undergoes a net conversion to B of 55%. If the reaction is elementary and a second identical reactor at the same temperature is placed downstream from the first, what is the overall conversion of A if, a) The reactors are directly connected in series b) The products from the first reactor are separated and only the unconverted A is fed to the second reactor
