Question

what is the difference between decomposition and dissociation reaction

Answer 1

Hey dear friend here your
answer :::

Decomposition ::
Whereas in decomposition a chemical compound breaks into two or more new chemical species i.e. Large molecules break into small new molecules.

For example

2H2O → 2H2 + O2.

Dissociation reaction ::
Dissociation is a general phenomenon in which the molecule breaks into atoms or ions.

H-Cl → H+ + Cl-

This is an example of dissociation of acid.

Thank you, good night
