A feed stream of 50 mol% A and 50 mol% 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 545 K, is at equilibrium, and contains 40 mol% C, 30 mol% A and 30 mol% B. Assuming CP = 80 J/mol•K for compound C, and that ?CP for the reaction is 0, what is ?HR0?
A. -1440 J/mol
B. -6300 J/mol
C. -3600 J/mol
D. 3600 J/mol
E. None of these
A. Incorrect. You are making a math mistake in your work.
