Statement A : Decomposition of ozone into oxygen results in the liberation of heat and an increase in entropy. Statement B : Ozone is thermodynamically unstable.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Ozone is thermodynamically unstable with respect to oxygen. This is because its decomposition into oxygen results in the liberation of heat (\(\Delta \mathrm{H}\) is negative) and an increase in entropy (\(\Delta \mathrm{S}\) is positive). So, the option (3) is correct.

Estimation of ozone can be made quantitatively by:
1 Oxidative ozonolysis method
2 Decomposition into \(\mathrm{O}_{2}\) and absorption of \(\mathrm{O}_{2}\) into pyrogallol
3 Volumetric method using KI and titration of liberated iodine using hypo solution
