Extracted text: A liquid-phase reaction A+ 2B→C is taking place in a semi-batch reactor. The reaction is begun with 84 moles of A in the reactor. The initial reactor volume is 50 liters. B is added at a volumetric rate of 2 lit/min and a concentration of 10 mol/lit. The reaction is assumed to be zero order with respect to both A and B. The rate constant k is 0.125 mol lit-min. How much time does it take to reach a conversion of 50% A. What is the concentration of B at this time?
