Rate Law

Reaction rate as a function of reactant concentrations.

Formula

r=k[A]m[B]nr = k[A]^m[B]^n

Variables

kRate constant
[A],[B]Concentrations
m,nOrders

Example

If a reaction is first order in A, doubling [A] doubles the reaction rate.

Did You Know?

A reaction's rate law can only be found by experiment, never guessed from the balanced equation.
