## initial vs overall units

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

### initial vs overall units

are units for initial concentration mol/L*s vs units for overall rate constant L/mol*s?
how do we know when to use one or the other?

### Re: initial vs overall units

I believe the units for the rate constant will depend on the order of the reaction. For example, if the reaction is first order, the units for k will be 1/s.
