The value of DeltaH("transition") of C (...

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^(@)`C

B

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

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
More heat is evolved due to combustion of less stable form.
