Determining the overall reaction and the molecularity of an elementary reaction : The following two - step mechanism hqas proposed for the gas-phase decomposition of nitrous oxide `(N_(2)O)` :
Step 1: `N_(2)O(g)rarrN_(2)(g)+O(g)`
Step 2: `N_(2)O(g)+O(g)rarrN_(2)(g)+O_(2)(g)`
(i) Write the chemical equation for the overall reaction
(ii) Identify any reaction intermediates
(iii) What is the molecularity of each of the elementary reactions ?
(iv) What is the molecularity of the overvall reaction
Strategy : The step-by -step pathway by which a reaction occurs is called its mechanism. Some reactions takes place in a single step, but most reactions occur in a series of elementary steps. To identify intermediates and molecularity, look at the indicidual steps
