Question:

The phase change between graphite and diamond is difficult to observe directly. Both substances can be burned, however. From these equations, calculate ΔH° for the conversion of diamond into graphite.

C(s, graphite) + O2(g) → CO2(g) ΔH° = –393.51 kJ C(s, diamond) + O2(g) → CO2(g) ΔH° = –395.94 kJ
