Considered a CSTR with constant heat capacity, negligible shaft work, ACp = 0, first order kinetics. All feeds enter at the same temperature and the CSTR is operated under a constant temperature. how does the graph of Xeb vs. temperature change for each of the scenarios below? Show your answer with a qualitative graph identifying the curve before and after the change in parameter. a. Contact area A is increased, and all other parameters remain the same. b. Ta is increased, and all other parameters remain the same. c. The active energy of the reaction is decreased, and all other parameters remain the same
