I am conducting the reaction shown in the balanced equation below. The reaction generally proceeds in the liquid phase, and reactants A and B are both liquid reactants; W is a gas phase reactant which is bubbled through the liquid in order to initiate the reaction. A is very valuable, so I want to do everything I can to get it to react, so I feed the other reactants in excess. The reactor has three outlets; one for the solid...
