Identify the molecularity of following elementary reaction?


Question: Identify the molecularity of following elementary reaction?

Hello and welcome to my blog, where I share my passion for chemistry with you. Today, I want to talk about a very important concept in chemical kinetics: the molecularity of elementary reactions.


What is an elementary reaction? It is a reaction that occurs in a single step, without any intermediates. For example, the reaction of hydrogen and iodine to form hydrogen iodide is an elementary reaction:


H2 + I2 -> 2HI


What is the molecularity of an elementary reaction? It is the number of molecules that collide and react in a single step. For example, the reaction above is a bimolecular reaction, because two molecules (H2 and I2) collide and react. Another example of a bimolecular reaction is:


NO + O3 -> NO2 + O2


A unimolecular reaction is one that involves only one molecule that undergoes a change. For example, the decomposition of ozone is a unimolecular reaction:


O3 -> O2 + O


A termolecular reaction is one that involves three molecules that collide and react in a single step. For example, the formation of nitric oxide from nitrogen and oxygen is a termolecular reaction:


N2 + 2O2 -> 2NO + O2


Termolecular reactions are very rare, because the probability of three molecules colliding at the same time and with the right orientation and energy is very low.


To summarize, the molecularity of an elementary reaction is the number of molecules that participate in a single-step reaction. It can be unimolecular, bimolecular or termolecular, depending on how many molecules collide and react.
