Chemical Reaction Engineering MCQs

An irreversible aqueous phase reaction, A + B → P, is carried out in an adiabatic mixed flow reactor. A feed containing 4 kmole/m3 of each A and B enters the reactor at 8 m3/hr. If the temperature of the exit stream is never to exceed 390 K, what is the maximum inlet feed temperature allowed? (Data: Heat of reaction = -50 kJ/mole, Density of the reacting mixture = 1000 kg/m3, Specific heat of reacting mixture = 2 kJ/kg.K) The above data can be assumed to be independent of temperature and composition.
