Sry by mistake it happened...For ozone it is +G

Abc Efg 7 years, 11 months ago

Yess afcourse ujjwal ozone prosses is endothermic

Bhumi Jain 7 years, 11 months ago

Here the ΔG(gibb's free energy is the determining factor.The chemical species with +G is considered to be thermodynamically unstable with respect to its element & they have spontaneous tendency to decompose to its constituents elements.For ozone it is -G &is thermodynamically unstable.The equilibrium constant for formation of ozone is less than one.But it survives because the reaction of decomposition of ozone to O2 is very slow.

But the ozone process endothermic

Abc Efg 7 years, 11 months ago

Ozone is thermodynamically less stable than oxygen because its decomposition into oxygen results in the liberation of heat. Ozone consists of three molecules of oxygen and thus in this its in unstable state so in order to get stable it gives up its one molecule of oxygen to restore diatomic state. Eventually, in all thus process large amount of heat is released.
