The decomposition of hydrogen peroxide in dilute sodium hydroxide at 20 °C is first order in H2O2. H2O2(aq)H2O(l) + ½ O2(g) During one experiment it was found that the H2O2 concentration dropped from 5.16×10-2 M at the beginning of the experiment to 1.95×10-2 M in 832 min. What is the value of the rate constant for the reaction at this temperature? min-1
