A liquid phase reaction, A+B à C+D is to be carried out in a well-mixed ideal batch reactor with a constant volume of 10 liters. The initial concentration of A is 4.71 mol/L, and the initial concentration of B is one half of the initial concentration of A. If the rate of formation of compound D is given by rD = k*CA*CB, with k = 4.5 L/(mol min), calculate the amount of time (in minutes) needed to achieve a conversion of the limiting reactant of 0.86.
