The <Arrhenius equation> is
$$
\boxed{k_1(T)=A\exp\!\left(-\frac{E_a}{RT}\right).}
$$
Here $E_a$ is the molar <activation energy>, $R$ the <molar gas constant>, $T$ the absolute <temperature>, and $A$ the <pre-exponential factor>, taken approximately constant over the measured range. For this bimolecular <elementary reaction>, $A$ and $k_1$ both have units $\mathrm{cm^3\,mol^{-1}\,s^{-1}}$.
