1A. The decomposition of dinitrogen monoxide (nitrous oxide) occurs in two steps. The mechanism that has been proposed is as follows: Step 1: N2O (g) à N2(g) + O(g) Step 2: N2O (g) + O(g) à N2(g) + O2(g) Write the chemical equation for the overall reaction and identify any reaction intermediates (spectators). What is the molecularity of each of the elementary (steps) reactions?
