Abstract:

There are several allotropes of carbon and their stability can be judged by energy criterion. Of the most common allotropes, graphite is the most stable under the standard condition, and its standard molar enthalpy of formation is taken as the reference value 0kJ/mol in physical chemistry. Recently, some researchers reported that diamond would be more stable than graphite at 0K. It should also be stressed that the claim that fullerene is more stable than graphite is wrong.

Key words: Carbon, Allotrope, Stability, Enthalpy of formation
