Vedclass · Answer

(C) The conversion of oxygen into ozone is an endothermic process $(\Delta H = +ve)$ and proceeds with a decrease in entropy $(\Delta S = -ve)$. The reaction is $3O_{2(g)} \rightleftharpoons 2O_{3(g)}$. According to the Gibbs free energy equation,$\Delta G = \Delta H - T\Delta S$. Since $\Delta H$ is positive and $\Delta S$ is negative,the term $-T\Delta S$ becomes positive. Thus,$\Delta G$ is always positive at all temperatures. Therefore,the reaction is non-spontaneous at all temperatures.
