Hello, my name is john, and for this question, concerning the rate law, rate equals the k constant, multiplied by the concentration of a to the power of 2, multiply by the concentration of b, what are appropriate units for the rate constant k? we have to group, following group answer choices.
00:20
So the first thing that we have to do is understand how the units of the k constant correlate to the powers that the concentrations in question are raised by.
00:31
So we have rate equals the k constant times the concentration of a squared times the concentration of b.
00:38
As we know, for one concentration, for example, to the power of one, its units of measurement is going to always equal malarity because that's what concentration is in regards to its units.
00:51
It's malarity.
00:52
Now, all we have to do now is take into account the number of concentrations and the sum of the powers that it's raised by for each respect to.
01:01
Concentration.
01:02
And in regard to that, it's going to be the total sum...
