In the reaction for the transition of carbon in the diamond form to carbon in the graphite form, `Delta H` is `-453.5` cal. This points out that

Options

A. Graphite is chemically different from diamond
B. Graphite is as stable as diamond
C. Graphite is more stable than diamond
D. Diamond is more stable than graphite

Answer

C

Explanation

`C_("Diamond")rarr C_("Graphite") , Delta H =-453.5` Cal
In exothermic reactions products are more stable than reactans, so graphite is more stable than diamond.
