Question


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 1.03 M-1 s-1 and a y-intercept of 13.4 M-1.

Based on this plot, the reaction is (frist, second, zero)__________   order in H2O2 and the rate constant for the reaction is _____________ M-1 s-1.
