Graphite

Vedclass · Answer

(A) The thermodynamic stability of carbon allotropes is determined by their standard enthalpy of formation. Graphite is the standard state of carbon,meaning its $\Delta H_f^{\circ} = 0 \ kJ \ mol^{-1}$. Other allotropes like diamond have a positive enthalpy of formation $(\Delta H_f^{\circ} = +1.9 \ kJ \ mol^{-1})$,making them less stable than graphite. The order of thermodynamic stability is: $	ext{Graphite} > 	ext{Diamond} > 	ext{Fullerene} > 	ext{Coke}$.
