One gram-atom of graphite and one gram-atom of diamond were separately burnt to `CO_(2)` . The amount of heat liberated was `393.5KJ` and `305.4KJ` respectively. It is apparent that

A

graphite has greater affinity for oxygen

B

diamond has greater affinity for oxygen

C

graphite is stabler than diamond

D

diamond is stabler than graphite.

Text Solution

Verified by Experts

The correct Answer is:
C
Since graphite on combustion give less heat, it means graphite has less heat content and is more stable.
