For the transition C (diamond) rarr C ...

For the transition
`C` (diamond) `rarr C` (graphite), `Delta H = - 1.5 kJ`
it follows that

A

diamond is exothermic

B

graphite is endothermic

C

graphite is more stable than diamond

D

diamond is more stable than graphite

Text Solution

Verified by Experts

The correct Answer is:
C
During the transformation of diamond to graphite, energy is released. This implies that graphite has lower energy content and, hence, is more stable than diamond.
