Carbon tetrachloride (ccl4) was once used as a refrigerant and a dry cleaning solvent until it was found to be severely toxic to the liver. the enthalpy of vaporization of ccl4 is 33.05 kj/mol and its normal boiling point is 76.72°c. what is its vapor pressure in atm at 57.8°c?

Answer : The vapor pressure of at is 0.519 atm.

Explanation :

The Clausius- Clapeyron equation is :

where,

= vapor pressure of at = ?

= vapor pressure of at normal boiling point = 1 atm

= temperature of =

= normal boiling point of =

= heat of vaporization = 33.05 kJ/mole = 33050 J/mole

R = universal constant = 8.314 J/K.mole

Now put all the given values in the above formula, we get:

Hence, the vapor pressure of at is 0.519 atm.
