Calculate `DeltaS` for following process :
`underset("at" 100K)(X(s)) underset("at" 200 K)(rarrX(l))`
Given : Melting point of `X_(s)=100K,DeltaH_("Fusion")=20kJ//"mol",C_(p.m)(X,l)=10J//"mol".K`

A

`26.93 J//K`

B

`206.93 J//K`

C

`203 J//K`

D

`206.93 kJ//K`

Text Solution

Verified by Experts

The correct Answer is:
B

`DeltaS=(20xx1000)/(100)+1xxunderset(100)overset(200)intC_(p m)(dT)/(T)`
`DeltaS=200+10ln2=200+10xx0.693`,
`DeltaS=206.93 " JK"^(-1)`
