Calculate the entropy changes of fustion...

Calculate the entropy changes of fustion and vaporisation for chlorine from the following data:
`Delta_(fus)H = 6.40 kJ mol^(-1)`, melting point `=- 100^(@)C`
`Delta_(vap)H = 20.4 kJ mol^(-1)`, boiling point `=- 30^(@)C`

Text Solution

Verified by Experts

`Delta_(fus)S = (6400)/(173K) = 36.9 J K^(-1) mol^(-1)`
`Delta_(vap)S = (20400)/(243) = 83.9 J K^(-1)mol^(-1)`
