Liquid water freezes at 273K under external pressure of 1atm . The process is at eruilibrium
`H_(2)O(l)toH_(2)O(S)at 273 Kand 1atm`
however , it required to calculate the thermodynamic parameters of the fusion process occurring at same pressure and different temperature . Using the following dat ,answer the questions thaat follow:
`d_(ice)=0.9gm //cc,d_(H_(2)O(l))=1gm //c"c",1L-atm =101.3 J `
`C_(p)[H_(2)O(s)]=36.4JK^(-1)mol^(-1)`
`C_(p)[H_(2)O(l)]=75.3Jk^(-1)mol^(-1)`
`DeltaH_("fusion")=6008.2mol^(-1).Alldataat 273K.`
`DeltaS_("fusion")`at 263 K and 1atm will be :

Options

A. `22.01JK^(-1)mol^(-1)`
B. `22.84JK^(-1)mol^(-1)`
C. `21.36JK^(-1)mol^(-1)`
D. `20.557JK^(-1) mol_(-1)`
