## Determining Order of the Reaction

$\frac{d[R]}{dt}=-k[R]; \ln [R]=-kt + \ln [R]_{0}; t_{\frac{1}{2}}=\frac{0.693}{k}$

### Determining Order of the Reaction

How do we determine the overall order of the reaction given a chemical equation and a rate?

add the order of the reactants
or look at the units of the rate

### Re: Determining Order of the Reaction

The rate of the reaction is equal to k([R]^n). The overall order is equal to n. For reactions with multiple reactants, (ex: A+B+C->D) the rate is equal to k([A]^n x [B]^m x [C]^l) and the overall order is equal to n+m+l.
