    Consider a kinetic study of oxidation of a new plastic stabiliser being proposed for the automobile industry.

    Stabiliser + H+ + O2 ----> Byproduct

    Trial [ Stabiliser] [H+] [O2] Rate (M min^-1)

    1 0.40 0.30 0.560 7.14 x 10^ -4
    2 1.20 0.30 0.560 2.14 x 10^ -3
    3 0.20 0.30 0.280 7.14 x 10^ -4
    4 0.40 0.60 0.560 1.43 x 10^ -3

    Fill in x, y, and z for: rate = k [Stabiliser]^x [H+]^y [O2]^z
    Circle the overall order of this reaction

    Show your calculations for working out the orders
    x =
    y=
    z=

    Overall order of rxn= pseudo first order zero order first order 2nd order 3rd order
    Explain why you chose this overall order for this rxn.

    Rate = k [Stabiliser]^x [H+]^y [O2]^z

    For trial 1: 7.14 x 10^ -4 = k (0.40)^x (0.30)^y (0.560)^z

    For trial 3: 7.14 x 10^ -4 = k (0.20)^x (0.30)^y ...

    Solution Summary

    The kinetic study of oxidation of a new plastic stabilizer being proposed is examined.
