The decomposition of hydrogen iodide on a gold surface at 150 °C HI(g)½ H2(g) + ½ I2(g) is zero order in HI. In one experiment, when the initial concentration of HI was 0.433 M, the concentration of HI dropped to 0.100 M after 1.74×10^3 seconds had passed. Based on these data, the rate constant for the reaction is M s-1.
