The MOLECULARITY of a reaction is 23 , so what does this means ?

please help soon.

thank you .

Molecularity of a reaction is the number of atoms, ions or molecules of reactant that must collide simultaneously with one another to give the product. 
For example    2H2 + O2 2H2
In the above reaction molecularity of reaction is 3.

Also,the possibility of simultaneous collision of four molecules in reaction is very less . So , molecularity of reaction can never exceed three. So,your question of molecularity of reaction is 23 is wrong.
