Question

In a chemical reaction one of the following can never be fraction

Answer 1

Answer:

Molecularity

Explanation:

Molecularity of reaction can never be a in fraction, it will always be whole number like 1, 2, 3 etc.

Molecularity is basically number of molecules taking part in chemical reaction. It can never be infinite, zero/imaginary.

It is pure theoretical value.  

For example the molecularity of below equation is 3 because in its 3 molecules are involved in reaction.

2CO + O2  →  2CO2
