Solution: Both graphite and diamond burn.C(s, diamond) + O2(g) ⟶ CO2(g)For the conversion of graphite to diamond:C(s, graphite) → C(s, diamond)                 ΔH° 298 = 1.90 kJWhich produces more heat, the com


Both graphite and diamond burn.

C(s, diamond) + O2(g) ⟶ CO2(g)

For the conversion of graphite to diamond:

C(s, graphite) → C(s, diamond)                 ΔH° 298 = 1.90 kJ

Which produces more heat, the combustion of graphite or the combustion of diamond?
