The enthalpy change for the transition of liquid water to steam is $40.8\mathrm{kJ}\mathrm{mol}^{-1}$ at 373 K. Calculate the entropy of vaporisation of water.

The entropy change for the fusion of 1 mol of a solid which melts at $27^{\circ}C$ is (latent heat of fusion $= 600\mathrm{cal}\mathrm{mol}^{-1}$)

For a process to be spontaneous

The equilibrium constant for a reaction is 10. \(\Delta G^\circ\) will be (\(R = 8 \, \text{J K}^{-1} \text{mol}^{-1}, T = 300 \, \text{K}\))
