Solution:
Explanation of Solution
Given information: The vapour pressure of benzene is
The temperatures of benzene are
The molar heat of vaporization,
The gas constant,
Convert the temperature in Kelvin:
Convert the heat in joule per mole as follows:
Now, calculate
Take antilogarithm on both the sides as follows:
Rearrange the above expression to obtain the vapor pressure as follows:

- 8.48 Why must the vapor pressure of a substance be measured only after dynamic equilibrium is established?arrow_forwardThe molar heat of fusion of sodium metal is 2.60 kJ/mol, whereas its heat of vaporization is 97.0 kJ/mol. a. Why is the heat of vaporization so much larger than the heat of fusion? b. What quantity of heat would be needed to melt 1.00 g sodium at its normal melting point? c. What quantity of heat would be needed to vaporize 1.00 g sodium at its normal boiling point? d. What quantity of heat would be evolved if 1.00 g sodium vapor condensed at its normal boiling point?arrow_forwardDiethyl ether (CH3CH2OCH2CH3) was one of the first chemicals used as an anesthetic. At 34.6C, diethyl ether has a vapor pressure of 760. torr, and at 17.9C, it has a vapor pressure of 400. torr. What is the H of vaporization for diethyl ether?arrow_forward
