1 (3 points) Write a detailed mechanism for the following reaction. Label the initiation, propagation, and termination steps clearly. light (CH3)3CH + Br2 (CH3)3CBr + HBr

2 (3 points) For the following reaction, when the [CH30¹] is doubled and the [(CH3)3CCl] is tripled, the initial rate of the reaction triples. Determine the rate law. Circle the correct answer. (CH3)3CC1 + CH30¹ → (CH3)3COCH3 + C₁¹- A rate = e = kr[CH30¹] B rate = kr[(CH3)3CC1] C rate = kr[(CH3)3CCI][CH30¹] D rate = kr[(CH3)3CCI] [CH30¹1³ E rate = k₁[(CH3)3CC1]³[CH30¹-₁² 3 (2 points) Label each of the hydrogen atoms in the following compound as 1º, 2º, or 3°.
