Interpretation:
Sublimation enthalpy of monoclinic sulfur has to be calculated using Clausius-Clapeyron equation.
Explanation of Solution
Clausius-Clapeyron equation can be given as,
Where,
If there are two sets of pressure and temperature, then the Clausius-Clayperon equation can be recast as shown below,
From the phase diagram, two pressure-temperature points can be estimated roughly. The obtained pressure and temperature is given below,
Sublimation enthalpy for monoclinic sulfur can be calculated by substituting the values in equation (2).
Rearranging the above equation, the sublimation enthalpy can be calculated,
Sublimation enthalpy of monoclinic sulfur is
