In the reaction for the transition of carbon in the diamond form to carbon in the graphite form, `DeltaH` is `-453.5` cal. This points out thatA. Graphite is chemically different from diamondB. Graphite is as stable as diamondC. Graphite is more stable than diamondD. Diamond is more stable than graphite

Answer» Correct Answer - C
`C_(D)rarrC_(G),DeltaH=-453.5 cal`.
i.e. energy of `C_(G)` is less and thus more stable.
