Consider a nonisothermal reactor in which the reaction Arightwards arrowD, is carried out adiabatically. The heat capacities of A and D are approximately equal to $20$J$/$mol$.$K and the shaft work is $$s$=0.$ When a conversion of $50\%$ is achieved in the reactor, the outlet temperature is $50$ K higher than the inlet. What is the heat of reaction $$HRx
