Assuming the compounds form ideal solutions, what is the flow rate of C in the exiting stream?

A feed stream of 50 mol/minof A and 50 mol/min of B at 500 K enter an adiabatic steady state reactor. The reaction is A + B ? C and occurs in the liquid phase. The stream leaving the reactor is at equilibrium. CP = 80 J/mol•K for compound C, and ?CP for the reaction is 0. At 298.15 K,?HR0 = -13 kJ/mol and ?GR0 = -20 kJ/mol. A. 0.0009 mol/min B. 32.63 mol/min C. 46.35 mol/min D. 47.45 mol/min E. 53.65 mol/min
