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.¶
\[
\ln\frac{[A]_t}{[B]_0}=-kt
\]
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.¶
\[
t_\frac{1}{2}=\frac{0.693}{k}
\]
Relationship between concentration and time for a second-order reaction.¶
\[
\frac{1}{[A]_t}=-kt+\frac{1}{[A]_0}
\]
