The height of Mt. Everest is 29,000' and the atmospheric pressure is 253 mmHg (0.333 atm). The gas constant R is 8.314J/K*mol and the heat of vaporization of water (AHvap) is 40.8 kJ/mol. The pressure at sea level is 760 mmHg. Note 1: The P₁ is the pressure at sea level and P₂ is the pressure on Mt. Everest. Note 2: The T₁ temperature is the boiling point of water at sea level which is 100 °C or 373 K. Note 3: The term AHvap is express in kJ/mol. This must be converted to J/mol. a) Using the two component Clausius-Clapeyron equation, determine the boiling point of water on the top of Mt. Everest. InP1/P₂= AHvap/R(1/T2-1/T1) 4
