At `0^@C` ,ice and water are in equilibrium and the enthalpy change for the process , `H_2O iff H_2O (l)` is ` 6kJ "mol"^(-1)` . Calculate the entropy change for the conversion of ice into water .

Text Solution

Verified by Experts

For the process , `H_2O (s) iff H_2O (l)`
`Delta S("fusion") = (Delta H ("fusion") )/("Freezing temp.")`
` = (6 xx 1000)/(273)`
` = 21.98 JK^(-1) "mol"^(-1)`
