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 PFR Low temperature in a CSTR High temperature in a PFR High temperature in a CSTR Low temperature in a PFR Low temperature in a CSTR ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Sometimes, batch process is preferred over continuous process, when the product Sales demand is fluctuating Both A & B Neither A nor B Quality & yield can not be achieved in continuous processes, because of long residence time Sales demand is fluctuating Both A & B Neither A nor B Quality & yield can not be achieved in continuous processes, because of long residence time ANSWER DOWNLOAD EXAMIANS APP
