Rate of reaction
$rate = - \frac{1}{a} \frac{d [ A ]}{d t} = + \frac{1}{b} \frac{d [ B ]}{d t}$
Rate law
$rate = k [A]^{m} [B]^{n}$
Order of reaction
$order = m + n$
Zero-order integrated
$[A] = [A]_{0} - k t$
Zero-order half-life
$t_{1/2} = \frac{[ A ] _{0}}{2 k}$
First-order integrated
$k = \frac{2.303}{t} lo g \frac{[ A ] _{0}}{[ A ]}$
First-order half-life
$t_{1/2} = \frac{0.693}{k}$
Second-order integrated
$\frac{1}{[ A ]} - \frac{1}{[ A ] _{0}} = k t$
Second-order half-life
$t_{1/2} = \frac{1}{k [ A ] _{0}}$
Arrhenius equation
$k = A e^{- E_{a} / R T}$
Arrhenius (log form)
$ln k = ln A - \frac{E _{a}}{R T}$
Two-temperature Arrhenius
$ln \frac{k _{2}}{k _{1}} = \frac{E _{a}}{R} (\frac{1}{T _{1}} - \frac{1}{T _{2}})$
Temperature coefficient
$\frac{k _{T + 10}}{k _{T}} \approx 2 to 3$
Units of rate constant
$k : (mol/L)^{1 - n} s^{- 1}$
Rate constant (zero order)
$k = mol L^{- 1} s^{- 1}$
Rate constant (first order)
$k = s^{- 1}$
Molecularity
$number of species in an elementary step$
Fraction remaining (first order)
$\frac{[ A ]}{[ A ] _{0}} = e^{- k t}$
Activation energy from graph
$slope of ln k vs \frac{1}{T} = - \frac{E _{a}}{R}$
Average rate
$avg rate = \frac{Δ [ A ]}{Δ t}$
Time for nth-life (first order)
$t = \frac{2.303}{k} lo g \frac{[ A ] _{0}}{[ A ]}$
Threshold energy
$E_{t h} = E_{a} + E_{r e a c t an t s}$
