In a study of the decomposition of nitrous oxide at 565 °C N₂O(g) N₂(g) + ½ O₂(g) the concentration of N₂O was followed as a function of time. It was found that a graph of 1/[N₂O] versus time in seconds gave a straight line with a slope of 1.63×10-³ M-¹ S-¹ and a y-intercept of 0.463 M-¹. Based on this plot, the reaction is M-¹ S-¹. order in N₂0 and the rate constant for the reaction is
