Melting point of a solid is x K and its ...

Melting point of a solid is x K and its latent heat of fusion is 600 cal `mol^(-1)`. The entropy change for fusion of 1 mol solid is 2 cal `mol^(-1)K^(-1)`. The value of x will be:

A

100K

B

200K

C

300K

D

400K

Text Solution

Verified by Experts

The correct Answer is:
C
`(DeltaH_("fusion"))/(T_("mp"))=DeltaS_(fusion)`
`(600)/(T)=2`
`T=300K`

The thermodynamic property that measures the extent of molecular disorder is called entropy. Entropy change of phase transformation can be calculated using Trouton's formula (DeltaS = DeltaH//T) . In the reversible adiabatic process, however, DeltaS will be zero. the rise in temperature in isobaric and isochoric conditions is found to increase the randomness or entropy of the system.
