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.

The value of DeltaH_("transition") of C (graphite) to C (diamond) is 1.9 kJ/mol at 25^(@) C entropy of graphite is higher than entropy of diamond. This implies that:

For conversion C (graphite) rarrC (diamond) the DeltaS is

Assertion (A): Enthalpy of graphite is lower than that of diamond. Reason (R ) : Entropy of graphite is lower than that of diamond.

Delta_(f) H of graphite is 0.23 kJ mol^(-1) and Delta_(f) H of diamond is 1.896 kh mol^(-1) . Delta H_(transition) from graphite to diamond is

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

C(s)("graphite") rarr C(g), DeltaH = 716.7 kJ DeltaH is the heat of ……………….of graphite.
