Chemical Reaction Engineering Calcination reaction of limestone (CaCO₃ → CaO + CO₂) goes to completion in the rotary kiln, because CO₂ escapes continuously Of high calcination temperature CaO is more stable than CaCO₃ CaO is not dissociated CO₂ escapes continuously Of high calcination temperature CaO is more stable than CaCO₃ CaO is not dissociated ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering In the gaseous phase ammonia formation reaction (N₂ + 3H₂ ⇋ 2NH₃), the value of the equilibrium constant depends on the Volume of the reactor Total pressure of the system Temperature Initial concentration of N₂ and H₂ Volume of the reactor Total pressure of the system Temperature Initial concentration of N₂ and H₂ ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering For identical flow rate, feed composition and for elementary first order reactions, 'N' equal sized mixed reactors in series with a total volume 'V' gives the same conversion as a single plug flow reactor of volume 'V' for constant density systems. This is true, when the value of 'N' is 1 >1 ≥1 ∞ 1 >1 ≥1 ∞ ANSWER DOWNLOAD EXAMIANS APP
