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.

A space velocity of 5 hr⁻¹ means that

Five reactor volumes of feed (at specified conditions) are being fed into the reactor per hour

After every 5 hours, reactor is being filled with the feed

Cent per cent conversion can be achieved in at least 5 hours

A fixed conversion of a given batch of feed takes 5 hours
