In a study of the decomposition of hydrogen iodide on a gold surface at 150 °CHI(g)½ H2(g) + ½ I2(g)the following data were obtained:[HI], M0.3400.1708.50E-24.25E-2seconds0521781911Hint: It is not necessary to graph these data.(1)The observed half life for this reaction when the starting concentration is 0.340 M is s and when the starting concentration is 0.170 M is s.(2)The average rate of disappearance of HI from t = 0 s to t = 521s is M s-1.(3)The average rate of disappearance of HI from t = 521s to t = 781s is M s-1.(4)Based on these data, the rate constant for this _______zerofirstsecond order reaction is M s-1.
