## Rate Laws

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

### Rate Laws

How do we know when a rate law should depend upon concentrations of products as well as reactants?

I think for this class, we consider the initial concentration of the reactant when finding the rate law because it is easier to study when there is little product formed.

I think unless otherwise stated you assume only the concentration of the reactants factor into the rate law because that makes it easier to study the rate without interferences.

### Re: Rate Laws

yeah i think for this class we do not need to consider the products' effects on the overall rate law for a reaction. however, if a product DOES have an effect on the overall reaction, then the reaction order for the product concentration would be a negative value in the overall rate law equation.
