In a study of the gas phase decomposition of hydrögen iödide at HI(g)V½ H2(9) + ½ I½(g) the concentration of HI was followed as a function of time. It was found that a graph of 1/[HI] versus time in seconds gave a straight line with a slope of 1.72×10 M1s1 and a y-intercept of 0.667 M. Based on this plot, the reaction is order in HI and the rate constant for the reaction is MIs
