Chemical Reaction Engineering The reactions of high molecularity are rare, because Of very large activation energy of many bodies Of requirement of very large concentration for such reactions Of low probability of many body collisions Many body collisions are not favoured energetically Of very large activation energy of many bodies Of requirement of very large concentration for such reactions Of low probability of many body collisions Many body collisions are not favoured energetically 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. 390 190 490 290 390 190 490 290 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering At a given temperature, K₁, K₂ and K3 are equilibrium constants for the following reactions 1, 2, 3 respectively. CH₄(g) + H₂O(g) ⇋ CO(g) + 3H₂(g), CO(g) + H₂O(g) ⇋ CO₂(g) + H₂(g) CH₄(g) + 2H₂O(g) ⇋ CO₂(g) + 4H₂(g) Then K₁, K₂ and K3 are related as: K3 = K₁.K₂ K3 = (K₁.K₂)2 K3(K₁+K₂)/2 K3 = (K₁.K₂)0.5 K3 = K₁.K₂ K3 = (K₁.K₂)2 K3(K₁+K₂)/2 K3 = (K₁.K₂)0.5 ANSWER DOWNLOAD EXAMIANS APP
