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 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 High temperature in a CSTR High temperature in a PFR ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering For a heterogenous catalytic reaction, A + B → C, with equimole feed of A and B, the initial rate - rA0 is invariant with total pressure. The rate controlling step is Surface reaction between absorbed A and absorbed B Surface reaction between A in the gas phase and absorbed B Surface Kc/(1 + TS) reaction between absorbed A and B in the gas phase Desorption of C Surface reaction between absorbed A and absorbed B Surface reaction between A in the gas phase and absorbed B Surface Kc/(1 + TS) reaction between absorbed A and B in the gas phase Desorption of C ANSWER DOWNLOAD EXAMIANS APP
