The enthalpy of vaporisation of liquid diethly ether `-(C_2H_5)_2O,` is `26.0kJmol(-1)` at its boiling point `(35.0^@C)`. Calculate `DeltaS` for conversion of : (a) liquid to vapour, and (b) vapour to liquid at `35^@C`.

Text Solution

Verified by Experts

(a). `DeltaS_("vaporisation")=(DeltaH_("vaporisation"))/(T_(bp))=(26000)/(308)`
`=84.42JK^(-1)mol^(-1)`
