The value of `DeltaH_("transition")` of C (graphite) `rarr` C (diamond) is 1.9 kJ/mol at `25^(@)C`. Entropy of graphite is higher than entropy of diamond. This implies that :A. C(diamond) is more themodynamically stable then C(graphite) at `25^(@)`CB. C(graphite)is more thermodynamically stable than C (diamond) at `25^(@)C`C. diamond will provide more heat on complete conbustion at `25^(@)C`D. `DeltaG_("transition")` of C(diamond) `rarr` C(graphite) is -ve

Answer» Correct Answer - B::C::D
More heat is evolved due to combustion of less stable form.
