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. 290 490 390 190 290 490 390 190 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering For the liquid phase parallel reactions:R, rR = K?.CA2; E? = 80 KJ/moleS, rS = K?.CA ; E? = 120 KJ/mole The desired product is R. A higher selectivity of R will be achieved, if the reaction is conducted at Low temperature in a CSTR Low temperature in a PFR High temperature in a CSTR High temperature in a PFR Low temperature in a CSTR Low temperature in a PFR High temperature in a CSTR High temperature in a PFR ANSWER DOWNLOAD EXAMIANS APP
