1. a) Starting with the second order rate law 𝑑[𝐴] / 𝑑𝑡 = −𝑘[𝐴]2 derive the integrated rate law in the form below: [𝐴] = [𝐴]0 /1+𝑘𝑡 [𝐴]0 (10 Marks)
b) Explain how the integrated rate law for first order andsecond order reactions can be used to determine whether thereaction is first or second order. (5 Marks)
c) Given the second order reaction. A → P If the initialconcentration of reactant “A” was 2.5M, determine the rate constantfor this second order reaction if after 2 minutes the concentrationof A was reduced to 0.667 of its initial concentration. (10Marks)
