## Rate laws for products vs reactants

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

### Rate laws for products vs reactants

Do zero order, first order, or second order rate laws change depending on if you are considering the products or the reactants?

Yes it would change if you were considering reactants(forward reaction) and then looking at products(reverse reaction). Your rate law would include the elements in either the reactants or products depending on if it is forward or reverse reaction.

The rate constants would change(if the equilibrium constant K does not equal 1), as could the order of the reaction depending on the actual rate of the reverse reaction. The laws will not change.
