Question
The value of ᐃHtransition of C (graphite) → C (diamond) is 1.9 kJ/mol at 25oC entropy of graphite is higher than entropy of diamond. This implies that :
Options
A.C (diamond) is more thermodynamically stable then C (graphite) at 25oC
B.C (graphite) is more thermodynamically stable than C (diamond) at 25oC
C.diamond will provide more heat on complete combustion at 25oC
D.ᐃGtransition of C (diamond) → C (graphite) is -ve
Solution
More heat is evolved due to combustion of less stable form.
