## mmol units

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

### mmol units

When finding rate laws and rate constants that usually have mmol in the units, do we always want to convert? In the textbook, it doesn't convert mmol in problem 14.17, but does convert them in problem 14.19.

I think you'd only need to convert so you can have the same units across. One of the problems has mmol and mol so units for mmol were converted to mol. But the other problem had only mmol units, so no conversion was necessary. The units of the initial rate and initial concentrations should match up.

For mmols you would need to divide by 1000 because 1000 mmols equals 1 mol. As long as they all have the same units, then the problem should be fine
