In this video, we want to determine the rate equation for this reaction that we're given initial rate data for.
00:10
So it's going to take the form of the rate as equal to some rate constant, multiplied by a to the order of the reactant a, multiplied by the concentration of b to the order of that reactant.
00:24
To find the orders, we have to look for a for two experiments.
00:30
Where b remains constant, so it has no effect.
00:32
So that looks like experiment 1 and experiment 2.
00:35
Now, a changes by a factor of 2 here, and the rate changes by a factor of 2 as well.
00:42
So if we call the order m, then 2 to whatever power m is equal to 2.
00:52
So the exponent that makes this true is 1.
00:55
So that's the order for a...
