![The Clausius-Clapyron equation
relates the latent heat of vaporization to
temperature and vapor pressure
according to the following equation:
AH,
In(p)=- +k
RT
Data for water are shown below (units
are K for T. mmHg for p. and J/mol. K for
R.)
a.) Use linear regression to find the
heat of vaporization of water.
The published value is 540 cal/g
b.) What will be the vapor pressure
in mmHg of water at 99°C
c.) Determine the Pearson r and
interpret the result.
