## Negative Order Reactions

$\frac{d[R]}{dt}=-k; [R]=-kt + [R]_{0}; t_{\frac{1}{2}}=\frac{[R]_{0}}{2k}$

### Negative Order Reactions

Is there such as thing as a negative order reaction (n<0)? What would this look like?

Hi! There actually are negative order reactions. A negative order indicates that the concentration of a species inversely affects the rate of the reaction. There is also the possibility for fractional orders of reactions.

What would the units for k be for rate laws with fractional and/or negative orders?
