Calculate the molar entropies Ss and Sg of the crystalline and vapor forms of I2 at 320 K with Eqs. (36) and (37), and obtain the molar heat of sublimation A//sub with Eq. (38). Compare it with the value obtained by the Clausius-Clapeyron method and with any literature values that you can find."... [Pg.535]

Because molecules are more tightly held in a sohd, the vapor pressure of a solid is generally much less than that of the corresponding liquid. Molar heat of sublimation (AHsub) of a substance is the energy (usually in kilojoules) required to sublime one mole of a solid. It is equal to the sum of the molar heats of fusion and vaporization ... [Pg.452]
