Question
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:
(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] = 0.4 and [B] = 1.2
[A] = 0.2 and [B] = 2.4
[A] = 0.2 and [B] = 3.6
[A] = 0.1 and [B] = 2.4
[A] = 0.3 and [B] = 1.2
[A] = 0.1 and [B] = 3.6
[A] = 0.5 and [B] = 1.2
[A] = 0.2 and [B] = 1.2
Experiment [A] (M) [B] (M) Rate (M/s) 1 0.1 1.2 2 0.2 1.2Explanation / Answer
reactant concentrations are [A] = 0.2M and [B] = 1.2M
