In a study of the decomposition of hydrogen iodide on a gold surface at 150 degree C HI(g) rightarrow 1/2 H_2(g) + 1/2 I_2(g) the following data were obtained: The observed half life for this reaction when the starting concentration is 0.133 M is s and when the starting concentration is 6.65 times 10^-2 M is s. The average rate of disappearance of HI from t = 0 s to t = 523 s is Ms^-1. The average rate of disappearance of HI from t = 523 s to t = 784 s is Ms^-1. Based on these data, the rate constant for this order reaction is Ms^-1.
