Chemical Reaction Engineering 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/mole, Density of the reacting mixture = 1000kg/m³, Specific heat of reacting mixture = 2kJ/kg.K)The above data can be assumed to be independent of temperature and composition. 190 390 490 290 190 390 490 290 ANSWER DOWNLOAD EXAMIANS APP
