Explain why ozone $(O_3)$ is thermodynamically less stable than oxygen $(O_2)$?

(N/A) The conversion of ozone $(O_3)$ to oxygen $(O_2)$ is an exothermic process,which means it is accompanied by the liberation of heat $(\Delta H < 0)$.
Additionally,the decomposition of $2$ moles of $O_3$ into $3$ moles of $O_2$ leads to an increase in entropy $(\Delta S > 0)$.
According to the Gibbs free energy equation,$\Delta G = \Delta H - T\Delta S$,both a negative $\Delta H$ and a positive $\Delta S$ result in a large negative value for the Gibbs free energy change $(\Delta G)$.
Since a negative $\Delta G$ indicates a spontaneous process,ozone is thermodynamically less stable than oxygen.
