Chemical Reaction Engineering With the same reaction time, initial concentration and feed rate, the reaction 2A → B is carried out separately in CSTR and P.F. reactor of equal volumes. The conversion will be Higher in P.F. reactor Data insufficient; can't be predicted Same in both the reactors Higher in CSTR Higher in P.F. reactor Data insufficient; can't be predicted Same in both the reactors Higher in CSTR ANSWER DOWNLOAD EXAMIANS APP
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
