Question

In a study of the gas phase decomposition of hydrogen peroxide at 400 °C, the reaction is represented as follows: H2O2(g) → H2O(g) + ½ O2(g). The following data were obtained: [H2O2], M: 0.180, 9.00×10-2, 4.50×10-2, 2.25×10-2 seconds: 0, 9.87, 29.6, 69.1 Hint: It is not necessary to graph these data. (1) The observed half-life for this reaction when the starting concentration is 0.180 M is s, and when the starting concentration is 9.00×10-2 M is s. (2) The average (1/[H2O2]) / t from t = 0 s to t = 9.87 s is M-1 s-1. The average (1/[H2O2]) / t from t = 9.87 s to t = 29.6 s is M-1 s-1. (3) Based on these data, the rate constant for this order reaction is M-1 s-1.
