When comparing rate constant at distinct temperatures, one can formulate the Arrhenius equation also in the following form: k2 Ea 1 1 会-会(*-*) = 六六一六) k1 R where K₁ and k₂ are the rate constants for a single reaction at two different absolute temperatures (T₁ and T₂).

The gas phase decomposition of dinitrogen pentoxide at 335 K N205(g)2 NO2(g) + ½ 02(g) is first order in N205. During one experiment it was found that when the initial concentration of N205 was 7.50×10-2 M, the concentration of N205 dropped to 2.09×10-2M after 198 s had passed. Based on this experiment, the rate constant for the reaction is || IS s-1.

The rearrangement of ammonium cyanate to urea in aqueous solution at 50 °C NHẠNCO(aq)→(NH2)½CO(aq) is second order in NH,NCO. In one experiment, when the initial concentration of NH4NCO was 0.136 M, the concentration of NH,NCO dropped to 3.75×102 M after 1.12×103 minutes had passed. Based on these data, the rate constant for the reaction is M min!.
