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 CSTR High temperature in a PFR Low temperature in a PFR Low temperature in a CSTR High temperature in a CSTR High temperature in a PFR Low temperature in a PFR Low temperature in a CSTR ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Batch process is preferred over continuous process, when the Product yields and quality can not be achieved in continuous process, because of long residence time Same equipment can not be used for several processes of the same nature Sales demand of product is not steady All of these Product yields and quality can not be achieved in continuous process, because of long residence time Same equipment can not be used for several processes of the same nature Sales demand of product is not steady All of these ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The response curve for a step input signal from a reactor is called C-curve. The variance of C-curve in a 'tanks in series model' comprising of 'm' tanks is equal to m² m √m 1/m m² m √m 1/m ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering In an ideal P.F.R. at steady state conditions There is no lateral mixing of fluid There may be diffusion along the flow path The conversion of the reactant varies from point to point along a flow path The composition of reactants remains constant along a flow path There is no lateral mixing of fluid There may be diffusion along the flow path The conversion of the reactant varies from point to point along a flow path The composition of reactants remains constant along a flow path ANSWER DOWNLOAD EXAMIANS APP
