The entropy of vaporization of water is 109.0 j/mol × k at its normal boiling point. what is the enthalpy of vaporization of wat
riadik2000 [5.3K]
The entropy of a system can be calculated by the ratio of the total heat in the system and the temperature. Entropy is a measure used in thermodynamics to approximate the degree of disorder in a system. From the equation for entropy, we can calculate the enthalpy as follows:

S = H / T
109.0 J / mol K = H / 373.15 K
H = 40673.35 J / mol
