To determine the rate constant, we first need to calculate the, or determine the order with respect to each reactant.
00:09
To do that, we'll look at experiments 1 and 2, where we see that the concentration of a is constant at 0 .02 molar, and only the concentration of b is changing.
00:25
It doubles.
00:26
When it doubles, we see that the rate doubles.
00:36
We go from 0 .01 to 0 .02 molar b, and the rate goes from 0 .001 to 0 .002.
00:45
So if what we do to the concentration, we do to the rate, this is representative of first order.
00:54
Essentially, we doubled the concentration, we doubled the rate.
00:59
If we raise the 2 to 1, we get to, that means its first order.
01:07
Now if we look at experiments 1 and 3, we see that only the concentration of a is changing...
