Recall: The Arrhenius equation gives us the relationship of the rate constant k with temperature and activation energy Ea. The two-point form of the Arrhenius equation is:

We're given:

k1 = 2.45 × 10–4 L/mol•s          T1 = 302 ˚C + 273.15 = 575.15 K

k2 = 0.891 L/mol•s                   T2 = 508°C + 273.15 = 781.15 K
