33.
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.

Xa is 1, as we need maximum temperature, which can only be achieved if a is converted fully.

How to get xa? Please explain it.

Convert the specific heat in unit of k mol instead of kg. From conc divide by density which gives kmol per kg.
Then apply xa=(Cpr(t2-t1))/(-Hr).
T2 will come 290.
