Question

The value of ΔH_transition of C (graphite) → C (diamond) is 1.9 kJ/mol at 25ºC entropy of graphite is higher than entropy of diamond. This implies that :

ΔG_transition of C (diamond) → C (graphite) is –ve

diamond will provide more heat on complete combustion at 25ºC

C (diamond) is more thermodynamically stable then C (graphite) at 25ºC

C (graphite) is more thermodynamically stable than C (diamond) at 25ºC
