Concept explainers
(a)
Interpretation:
Calculate the vapor pressure of ethylene diamine at each temperature.
Concept introduction:
Pressure exerted by a liquid column exposed to atmosphere can be calculated as,
Pressure = pressure due to liquid + atmospheric pressure
(b)
Interpretation:
Use a graphical method to estimate the normal boiling point and the heat of vaporization of ethylene diamine.
Concept introduction:
Clausius-Clapeyron equation
If the vapor pressure is known for a given temperature, then we can use this equation to calculate the vapor pressure at different temperatures.
(c)
Interpretation:
Does the Clausius-Clapeyron equation satisfied for the given case.
Concept introduction:
Clausius-Clapeyron equation
If the vapor pressure is known for a given temperature, then we can use this equation to calculate the vapor pressure at different temperatures.
