Use vapor pressure data for water (from Antoine Equation) to determine deltaH(vapor) for water at 150 degrees C. Use both the Clapeyron Equation and the Clausius-Clapeyron Equation. Data from the steam tables show that deltaV(vapor) = 7045.2 cm^3/mol at 150 degrees C. Compare your results for each equation, as well as with the value from the steam tables.
