Here we're given three graphs.
00:02
One of the concentration is a function of time.
00:08
The other, natural log of concentration, is a function of time.
00:15
And that gives us a straight line.
00:18
And then, one over the concentration, as a function of time.
00:27
So because the straight line is with natural log, that tells us that it is first order in a.
00:34
So the rate law, well they don't ask for the rate law, so first order, looks like that's the first answer that i will call a.
00:44
Now knowing it's first order, we can use the first order integrated rate law to calculate the k value, the rate constant.
00:52
The natural log of the amount at time t, over the amount at time zero, or concentration at time t, over concentration at time zero, equals negative kt...
