Chemical Reaction Engineering In the hydrodealkylation of toluene to benzene, the following reactions occur:C₇H₈ + H₂ → C₆H₆ + CH₄2C₆H₆ ⇋ C₁₂H₁₀ + H₂Toluene and hydrogen are fed to a reactor in a molar ratio 1:5.80% of the toluene gets converted and the selectivity of benzene(defined as moles of benzene formed/moles of toluene converted) is 90%. The fractional conversion of hydrogen is 0.152 0.144 0.136 0.16 0.152 0.144 0.136 0.16 ANSWER DOWNLOAD EXAMIANS APP
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 Higher in CSTR Same in both the reactors Data insufficient; can't be predicted Higher in P.F. reactor Higher in CSTR Same in both the reactors Data insufficient; can't be predicted ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The performance of a cascade of CSTR's can be improved by adding A P.F. reactor in parallel More CSTR's in parallel A P.F. reactor in series More CSTR's in series A P.F. reactor in parallel More CSTR's in parallel A P.F. reactor in series More CSTR's in series 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)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 K3 = K₁.K₂ ANSWER DOWNLOAD EXAMIANS APP
