Use the Standard Entropies for Liquid Water and Steam to Estimate

question 22

Short Answer

Use the standard entropies for liquid water and steam to estimate the enthalpy of vaporization of water at its normal boiling point. $\Delta$ S ^$\circ$ [H₂O( )] = 69.9 J/K.mol and $\Delta$ S ^$\circ$ [H₂O(g)] = 188.8 J/K.mol.
