Chemical Reaction Engineering In the reversible reaction of the type, A + B ⇋ AB, in general The combination reaction will be exothermic, while the dissociation reaction will be endothermic Both forward and backward reactions will be exothermic Neither of the reactions will be en-dothermic The combination reaction will be endothermic, while the dissociation reaction will be exothermic The combination reaction will be exothermic, while the dissociation reaction will be endothermic Both forward and backward reactions will be exothermic Neither of the reactions will be en-dothermic The combination reaction will be endothermic, while the dissociation reaction will be exothermic ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering In an ideal P.F.R. at steady state conditions There is no lateral mixing of fluid There may be diffusion along the flow path The conversion of the reactant varies from point to point along a flow path The composition of reactants remains constant along a flow path There is no lateral mixing of fluid There may be diffusion along the flow path The conversion of the reactant varies from point to point along a flow path The composition of reactants remains constant along a flow path 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. 490 190 390 290 490 190 390 290 ANSWER DOWNLOAD EXAMIANS APP
