The irreversible elementary reaction, 2A --> B, takes place in the gas phase in an isothermal PFR. Reactant A and a diluent C are fed in equimolar ratio, and conversion of A is 80%. If the molar feed rate of A is cut in half, what is the conversion of A assuming the feed rate of C is left unchanged? Assume ideal gas behavior and that the reactor temperature remains unchanged. Use the Damkohler number to compare the two situations.
