Answer
i) H2O2(g) ------> 2OH(g)
Explanation
Rate law = k [H2O2]
step1 involved H2O2 only as the reactant, step2 is involved OH also as reactant and step3 is not involved H2O2 as a reactant . So, step1 must be the rate determing steps.

In a study of the gas phase decomposition of hydrogen peroxide at 400 °C H2O2(g)----->H2O(g) + ½ O2(g) the concentration of H2O2 was followed as a function of time. It was found that a graph of 1/[H2O2] versus time in seconds gave a straight line with a slope of 0.884 M-1 s-1 and a y-intercept of 7.04 M-1. Based on this plot, the reaction is _______zerofirstsecond order in H2O2 and the rate constant for the reaction is M-1 s-1.
