Concept explainers
(a)
Interpretation: The approximate vapor pressure curve for
Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form.
When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure.
If intermolecular force is small the vapor pressure of the substance is high and the boiling point will be low.
(b)
Interpretation: From the vapor pressure curve for
Concept Introduction:
Intermolecular force: The attractive force that withholds two molecules is called as intermolecular force. The influence of intermolecular forces depends on molar mass and the
Dipole-Dipole Interactions: The attractive force that holds two polar molecules with help of dipole moment present in them is called as Dipole-Dipole Interactions.
The partial positive charge end of one molecule is attracted to the partial negative charge of a neighboring molecule.
Induced Dipole - Induced Dipole Forces: The attractive force that holds two nonpolar molecules with help of temporary dipole moment present in them is called as induced dipole-induced dipole forces.
(c)
Interpretation: The normal boiling point of
Concept Introduction:
Boiling point: It is the temperature at which liquid converts to vapor. At boiling point the vapor pressure of liquid and the pressure of the surroundings are equal.
(d)
Interpretation: The temperature at which

- The vapor pressure of ethanol, C2H5OH, at 50.0 C is 233 mmHg, and its normal boiling point at 1 atm is 78.3 C. Calculate the vapH of ethanol.arrow_forwardChloroform, CHCl3, has a normal boiling point of 61C. Its vapor pressure at 43C is 0.526 atm. What is the concentration (in g/L) of CHCl3 when it saturates the air at 27C?arrow_forwardA 1.50-g sample of methanol (CH3OH) is placed in an evacuated 1.00-L container at 30 C. (a) Calculate the pressure in the container if all of the methanol is vaporized. (Assume the ideal gas law, PV = nRT.) (b) The vapor pressure of methanol at 30 C is 158 torr. What mass of methanol actually evaporates? Is liquid in equilibrium with vapor in the vessel?arrow_forward
