Chemical Reaction Engineering Calcination reaction of limestone (CaCO₃ → CaO + CO₂) goes to completion in the rotary kiln, because CaO is more stable than CaCO₃ CO₂ escapes continuously Of high calcination temperature CaO is not dissociated CaO is more stable than CaCO₃ CO₂ escapes continuously Of high calcination temperature CaO is not dissociated ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is 2 0 3 1 2 0 3 1 ANSWER DOWNLOAD EXAMIANS APP
