1. a) Starting with the second order rate law d[A]= dt derive the integrated rate law in the form below: [A] = [A]o 1+kt [A]o -k[A]² (10 Marks) b) Explain how the integrated rate law for first order and second order reactions can be used to determine whether the reaction is first or second order. (5 Marks) c) Given the second order reaction. A → P If the initial concentration of reactant "A" was 2.5M, determine the rate constant for this second order reaction if after 2 minutes the concentration of A was reduced to 0.667 of its initial concentration. (10 Marks) 2. a) Briefly discuss the concept of Drift Speed (s) of an ion of an electrolyte when the ion experiences an applied electrical field. (5 Marks) b) With reference to the relationships u and λ = zuF ze όπηα Explain how the factors relating to the ion and solvent influence the molar conductivity of an ion. (10 Marks) c) State and explain the three main steps in a chain reaction. (10 Marks) 3. a) With the use of appropriate examples explain the difference between the conductivities of strong and weak electrolytes. (5) b) Compare and contrast Oswald's Dilution Law and Kohlrauch's Law. (10) c) Explain the plot based on the Ostwald's Dilution Law. State the parameters that can be obtained from this plot. (10)
