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 3 0 1 2 3 0 1 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering For the liquid phase parallel reactions:R, rR = K?.CA2; E? = 80 KJ/moleS, rS = K?.CA ; E? = 120 KJ/mole The desired product is R. A higher selectivity of R will be achieved, if the reaction is conducted at High temperature in a PFR High temperature in a CSTR Low temperature in a CSTR Low temperature in a PFR High temperature in a PFR High temperature in a CSTR Low temperature in a CSTR Low temperature in a PFR ANSWER DOWNLOAD EXAMIANS APP
