NEET levelSingle correct optionDifficulty 1 of 3pn061

The decomposition $2 O X_{3} 3 O X_{2}$ is exothermic. It follows that ozone is

Aas stable as dioxygen
Bstable at all temperatures but reacts slowly
Cless stable than dioxygen
Dmore stable than dioxygen

Answer: C

Energy is released when ozone changes into dioxygen and entropy also increases, so

Δ G < 0

. Ozone is therefore thermodynamically less stable than

O X_{2}

.
