Gce Model Questions Vol1 2024 Chemistry Question 3
Practice objective / multiple choice question 3 from the 2024 Gce Model Questions Vol1 Chemistry examination.
The enthalpy of sublimation of graphite to gaseous carbon atoms at 298 K is 716 kJ mol⁻¹. The enthalpy change for the conversion of graphite to diamond at the same temperature is +1.9 kJ mol⁻¹ (diamond is less stable). Assuming that each carbon atom in diamond is tetrahedrally bonded to four neighbours and that all C-C bonds have the same energy, calculate the average C-C bond energy in diamond (in kJ mol⁻¹).
