# reaction rate lawZoomA-Z

## Subject - Physical Chemistry

The reaction rate law expresses the dependency of the $r$ on the concentrations of substances A,B,C.. that participate in a reaction.

$r=f([A],[B],[C],...)$

Frequently, function $f$ is shown as the product

$r=k[A]a[B]b[C]c···$

where $k$ is the reaction rate constant and $a$, $b$, $c$, ... are the reaction orders regarding compounds A, B, C, ...

Short forms for the reaction rate law are rate law or rate equation.
