Many chemicals release harmful volatile compounds into the atmosphere that need to be controlled during use. In the process given below, the amount of CO at the outlet is greatly reduced by passing the effluent leaving the reactor through a separator and feeding back the unreacted CO along with the reactant. Although the name of the product in question is unknown because it is patented, it is known that the fresh feed stream contains 40% reactant, 50% inert and 10% CO, and 2.5 moles of product are obtained from 2 moles of reactants. The conversion of reactant to product was found to be 73% for a single pass through the reactor and 90% for the entire process. Since the return flow contains 80% CO and 20% reactants, find the ratio of the return flow to the product flow in moles. (All % 's are molce).
