In this video, we are going to determine the units for a rate constant k given the rate law.
00:06
So basically, what we can do is we can write the units of the rate and the units of concentration raised to all these powers and then solve for the rate of k.
00:13
First, i want to rearrange this so that it's written in terms of k.
00:17
So if we divide both sides by a to the fourth times b times c squared, and we'll get that k is equal to the rate divided by each of the concentrations raised to their powers, like so.
00:32
And then we can go ahead and plug in.
00:33
So the rate is going to be in concentration or molarity per second.
00:37
And then each of these concentrations are molarities, but they'll be raised to a certain power.
00:41
So a will be molarity to the fourth, b will be molarity to the first.
00:46
So we'll check the m and then c will be molarity squared...
