In a study of the gas phase decomposition of hydrogen iodide at 700 K HI(g)½ H2(g) + ½ I2(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 1.68×10-3 M-1 s-1 and a y-intercept of 2.66 M-1. Based on this plot, the reaction is ______ (zero/first/second) order in HI and the rate constant for the reaction is _____...
