Question

What is the enthalpy of atomization? Give an example.

✓

Answer

Enthalpy of atomisation $\left(\Delta_{\text {atom }} H \right)$ : it is the enthalpy change accompanying the dissociation of one mole of gaseous substance into its atoms at constant temperature and pressure.
For example : $CH _{4( g )} \rightarrow C _{( g )}+4 H _{( g )} \Delta_{ atom } H =1660 kJ mol ^{-1}$
