k2 = 0.2. Equimolar quantities of solutions of A, B and D are fed continuously to a CSTR where they react according to two elementary reactions: A+DR ki B+DS k2 where ki (a) If 50% of incoming A is consumed, determine what fraction of the products (R + S) formed is R. (b) If 50% of incoming D is consumed, determine what fraction of the products (R + S) formed is R. Ans: (a) 0.75 (b) 0.775
