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.
