## Order of rxns and stoichiometric coefficients

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

### Order of rxns and stoichiometric coefficients

Will the order of a reaction with respect to a single reactant ever be the stoichiometric coefficient of that reaction in the balanced chemical equation?

It is a possibility that they could be the same, but the stoichiometric coefficients don't actually correspond to the reaction order.

They are not necessarily the same, but in some occasions they are. It is best not to assume they are the same and to find the order itself.

### Re: Order of rxns and stoichiometric coefficients

They can coincidentally be the same value, but we can't set the order of reaction based off stoichiometric coefficients. It takes some work, but calculating and determining the order from the experimental data is the best and only way to get the right order.
