The enthalpy of vapourization of liquid is 30 kJ mol−1 and entropy of vaporization is 75 kJ/mol. The boiling point of the liquid at 1 atm is
250 K
400 K
450 K
600 K
ΔS = ΔQrevT; 75 = 30 × 103T
∴ T = 400 K
The enthalpy of vaporisation of liquid is 30KJ/mol and entropy of vaporisation is 75J/mol/k. The Boiling point of the liquid at 1 atm is
