You and your lab partner are studying the rate of a reaction, A B --> C. You make measurements of the initial rate under the following conditions: Experiment[A] (M)[B] (M)Rate (M/s) 10.60.7 21.20.7 (a) Which of the following reactant concentrations could you use for experiment 3 in order to determine the rate law, assuming that the rate law is of the form, Rate = k [A]x [B]y? Choose all correct possibilities. [A] = 0.6 and [B] = 2.1 [A] = 3.0 and [B] = 0.7 [A] = 1.2 and [B] = 2.1 [A] = 0.6 and [B] = 1.4 [A] = 1.8 and [B] = 0.7 [A] = 2.4 and [B] = 0.7 [A] = 1.2 and [B] = 0.7 [A] = 1.2 and [B] = 1.4
