In a study of the decomposition of nitrous oxide at 565C N2O(g)N2(g)+1/2O2(g) the following data were obtained: Hint: It is not necessary to graph these data. (1) The observed half life for this reaction when the starting concentration is 0.417M is s and when the starting concentration is 0.209M is s. (2) The average (1/[N2O])/t from t=0s to t=2.83103s is M1s1. The average (1/[N2O])/t from t=2.83103s to t=8.45103s is M1s1 (3) Based on these data, the rate constant for thi rder reaction is M1s1
