A reacts with B to give a product, C. A also reacts to give an unwanted side product, D according to the reactions given below: (the reactions follow elementary kinetics.) A+2B3CA2D 1.1 If the reaction for the desired product above has elementary kinetics, what is the rate of reaction of A for the first reaction only? Use k1A for your rate constant. [2] 1.2 the reaction for the unwanted product above has elementary kinetics, what is the rate of reaction of A for the second reaction only? Use k2A for your rate constant. [2] 1.3 What is the net rate of reaction of A ? 1.4 What is the rate of reaction of B relative to A and the net rate of reaction of B ? [3] 1.5 What is the rate of reaction of C relative to A and the net rate of reaction of C ? [3] 1.6 What is the rate of reaction of D relative to A and the net rate of reaction of D ? [3] 1.7 What is the instantaneous selectivity of C with respect to D, i.e. SCD ? [2] 1.8 By considering the reaction orders of the rate equations, which type of reactor would you choose in order to minimise the unwanted side product? [2]
