## Reaction Rate Constant Units

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

### Reaction Rate Constant Units

Just to clarify, depending on the order, like zero, first, second, etc. order, the reaction rate constant units would differ right? For example, for a third order reaction, would the units for the reaction rate constant would be $\frac{L^2}{mol^2*s}$? Thanks!

Yeah I'm pretty sure you're right!

Yes, that is correct! For second order reactions, the units are L^2/(mol^2 * seconds).
