## reaction rate(s)?

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

### Re: reaction rate(s)?

The rate law is an equation that gives you the reaction rate.

For example:
$r=k[A][B]$

$r$ is the rate, and $r=k[A][B]$ is the rate law.

A reaction rate compares the change in concentration over time. A rate law relates the rate of reaction to the concentrations of the reactants which are modified by an exponent representing the reaction order.

When does the reaction rate also depend on the concentration of the products?

Reaction rate is the actual rate while rate law is the formula (ex. rate=k[A])
