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. 190 390 290 490 190 390 290 490 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)0.5 K3 = (K₁.K₂)2 K3(K₁+K₂)/2 K3 = K₁.K₂ K3 = (K₁.K₂)0.5 K3 = (K₁.K₂)2 K3(K₁+K₂)/2 ANSWER DOWNLOAD EXAMIANS APP
