Heat of combustion of graphite is \mathrm{94.052 \mathrm{Kcal} / \mathrm{mol}} and that of diamond is \mathrm{94.505 \mathrm{kcal} / \mathrm{mol}}. However, it can be converted into diamond at \mathrm{16000^{\circ} \mathrm{C}} by a pressure of \mathrm{5000 \: to \: 60000 \mathrm{~atm}}. Graphite is more reactive than diamond due to the presence of mobile electron on each carbon atom.

Hence option 2 is correct.
