Question: An irreversible aqueous phase reaction, A + B P, is carried out in an adiabatic mixed flow reactor. A feed containing 4kmole/m3 of each A and B enters the reactor at 8m3 /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/moleDensity of the reacting mixture = 1000kg/m3Specific heat of reacting mixture = 2kJ/kg.K The above data can be assumed to be independent of temperature and composition.
