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) 1 1.6 0.4 2 3.2 0.4 (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] = 3.2 and [B] = 0.8 [A] = 1.6 and [B] = 1.2 [A] = 3.2 and [B] = 0.4 [A] = 3.2 and [B] = 1.2 [A] = 4.8 and [B] = 0.4 [A] = 6.4 and [B] = 0.4 [A] = 8.0 and [B] = 0.4 [A] = 1.6 and [B] = 0.8 (b) For a reaction of the form, A + B + C --> Products, the following observations are made: tripling the concentration of A increases the rate by a factor of 3, doubling the concentration of B has no effect on the rate, and tripling the concentration of C increases the rate by a factor of 27. Select the correct rate law for this reaction from the choices below. Rate = k[A][B][C]Rate = k[A][C] Rate = k[A]2 [C]Rate = k[A][C]2Rate = k[A]2 [C]2 Rate = k[A]3 [C] Rate = k[A][C]3 (c) By what factor will the rate of the reaction described in part (b) above change if the concentrations of A, B, and C are all halved (reduced by a factor of 2)? The rate will be the original rate multiplied by a factor of .___
