Heat Exchange Elementary gas phase reaction carried out in a PBR The feed consists of both inerts I and Species A with the ratio of inerts to the species A being 2 to 1. (a) Adiabatic. Plot X, X e , T and the rate of disappearance as a function of V up to V = 40 dm 3 . (b) Constant T a . Plot X, X e , T, T a and Rate of disappearance of A when there is a heat loss to the coolant and the coolant temperature is constant at 300 K for V = 40 dm 3 . How do these curves differ from the adiabatic case? (a) Variable T a Co-Current . Plot X, X e , T, T a and Rate of disappearance of A when there is a heat loss to the coolant and the coolant temperature varies along the length of the reactor for V = 40 dm 3 . The coolant enters at 300 K. How do these curves differ from those in the adiabatic case and part (a) and (b)? (d) Variable T a Counter Current . Plot X, X e , T, T a and Rate of disappearance of A when there is a heat loss to the coolant and the coolant temperature varies along the length of the reactor for V = 20 dm 3 . The coolant enters at 300 K. How do
