The decomposition of hydrogen peroxide in dilute sodium hydroxide at 20 °C H2O2(aq)H2O(l) + ½ O2(g) is first order in H2O2 with a rate constant of 1.10×10-3 min-1. If the initial concentration of H2O2 is 5.66×10-2 M, the concentration of H2O2 will be 9.34×10-3 M after _______ min have passed.
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.
