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.

Sometimes, batch process is preferred over continuous process, when the product

Quality & yield can not be achieved in continuous processes, because of long residence time

Sales demand is fluctuating

Neither A nor B

Both A & B

The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the

Collision frequency increases

Fraction of molecules having threshold energy increases

Increased temperature reduces the activation energy

Value of threshold energy decreases
