Chemical Reaction Engineering Batch process is preferred over continuous process, when the Same equipment can not be used for several processes of the same nature Sales demand of product is not steady Product yields and quality can not be achieved in continuous process, because of long residence time All of these Same equipment can not be used for several processes of the same nature Sales demand of product is not steady Product yields and quality can not be achieved in continuous process, because of long residence time All of these ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Rate of a chemical reaction is not influenced by the Catalyst Temperature Reactants concentration Number of molecules of reactants taking part in a reaction Catalyst Temperature Reactants concentration Number of molecules of reactants taking part in a reaction ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Semibatch reactor is preferred, when a/an A highly exothermic reaction is to be controlled A gas is to be reacted with liquid (e.g. hydrogenation of fat) Undersirable side reaction (at high concentration of one of the reactants) is to be avoided All of these A highly exothermic reaction is to be controlled A gas is to be reacted with liquid (e.g. hydrogenation of fat) Undersirable side reaction (at high concentration of one of the reactants) is to be avoided All of these ANSWER DOWNLOAD EXAMIANS APP
