the correct answer is 15.2

The liquid phase reversible reaction RT is carried out in an ideal mixed flow reactor. The concentrations of R and T that enter the reactor are, respectively, 4.85 and 0 (zero) mol/L. The rate constant of the forward reaction is 7.28min 1, and the equilibrium constant, based on concentration, Kc, is 3 . What is the required reactor volume (in Liters, expressed to one decimal place) that is needed to achieve a conversion, X, that is 98% of the equilibrium conversion (i.e. X is 0.98Xe )? You may assume that the forward and reverse reactions are elementary, and the entering molar flowrate of pure R is 14.61mol/min. 15.2 margin of error +15%
