Consider the following reaction, the bromination of acetone. (ch3)2co + br2 → ch3coch2br + hbr a series of experiments is performed to determine the rate law of the reaction. the experiments yield the following data. experiment [br2]o (m) [(ch3)2co]o (m) initial rate (m/s) 1 0.22 0.22 7.21 ✕ 10−5 2 0.22 0.44 1.44 ✕ 10−4 3 0.44 0.44 1.44 ✕ 10−4 (a) determine the reaction order for each reactant and the overall reaction order. acetone: zero order first order second order third order bromine: zero order first order
