Equations

Rate law expressions. The sum ($x+y$) gives the overall order of the reaction.

rate=k[A]x[B]y

Relationship between concentration and time for a first-order reaction.

ln[A]t[B]0=kt

Equation for the graphical determination of $k$ for a first-order reaction.

ln[A]t=kt+ln[A]0

Half-life for a first order reaction.

t12=0.693k

Relationship between concentration and time for a second-order reaction.

1[A]t=kt+1[A]0
