For the competing reactions: A+Bk1y,k1rC2A+Ck22Q C is the desired product and Q the undesired product. If the rates of reaction of A for each of the reactions are: r1A=k1fCACBA+k1rCCr2C=k2CA2CC 1.1 Are these reactions series, parallel or complex? [2] 1.2 What is the net rate of reaction for each of the species in the reactions above written in terms of the rate constants and the concentrations of A,B and C ? [17] 1.3 What are the units of k1,k1r and k2 (use L,mol and s)? 1.4 Write an expression for the instantaneous selectivity, S^C/Q and explain how you would maximise the production of C. 1.5 Write an expression for the overall selectivity, SC/
