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:

Experiment [A] (M) [B] (M) Rate (M/s)
1 0.3 1.7
2 0.6 1.7


(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] = 1.7
[A] = 0.6 and [B] = 5.1
[A] = 1.5 and [B] = 1.7
[A] = 0.3 and [B] = 3.4
[A] = 1.2 and [B] = 1.7
[A] = 0.3 and [B] = 5.1
[A] = 0.6 and [B] = 3.4
[A] = 0.9 and [B] = 1.7

Explanation / Answer

[A] = 0.6 and [B] = 5.1 [A] = 0.3 and [B] = 3.4 [A] = 0.3 and [B] = 5.1 [A] = 0.6 and [B] = 3.4
