Question

Carbon occurs in two forms, graphite and diamond. The enthalpy
of the combustion of graphite is -393.5 kJ/mol, and
that of diamond is -395.4 kJ/mol:
C(graphite) + O₂(g)----->CO₂(g) ΔH = -393.5 kJ
C(diamond) + O₂(g)----->CO₂(g) ΔH = -395.4 kJ
Calculate ΔH for the conversion of graphite to diamond:
C(graphite)-----> C(diamond) ΔH = ?
