Sapling Week 9 and 10 Question #7 [ENDORSED]

[Amanda Bueno-Kling]

I have done most of this question, but I am stuck on the part that asks:
Calculate the rate constant, k, and identify its units.
I found that rate=k[A][B]^2
But I am not sure what do to find K. Do I plug in a set of values from the table?

[Joyce Pang 2H]

You can plug in the values from any experiment to find k -- they should all yield the same answer anyway.

Thank you!
I did 9.8=k[16][175]^2 and solved for k to get 0.00002, which was correct.

Hello! In order to find k, you can plug in any of the values from the experiments. For instance, in experiment 2, your equation would be as follows, 19.6 = k[32][175]^2. Ultimately, you would have to isolate k, and the result would be k = 0.00002.
