Interpretation:
Vapour pressure is pressure exerted by vapour when its pure condensed phase condensed phase (solid orliquoid) is in equilibrium with gas phase (Vapour) vapour pressure is function temper ature for a given pure form vapour pressure of a substance is instrisic property. There are there 1.0L flasks, maintained at 308Kare connected to each other with stop cocks, initially, the stop cock s are closed, there three are opened and missed you have to find out final pressure of mixture. Initially each flaks are maintained at temperature 308K.
In the first flask N2 is kept at 1 atom.
In the second flask 2.0g of H2O His kept and in third flask 0.50g of ethanol is kept.
It is given that the vapour pressure of H2O at 308K is 4233Hg and that of ethanol is 102mmHg.
Concept introduction:
Total pressure inside the flask is summation of pressure due to each component
Ptotal> =PN2+PH2O+PC2H6o

(Limonene is used as a scent in commercial products.) (a) Plot these data as ln P versus 1/T so that you have a graph resembling the one in Figure 11.13. (b) At what temperature does the liquid have an equilibrium vapor pressure of 250 mm Hg? At what temperature is it 650 mm Hg? (c) What is the normal boiling point of limonene?

What are dipole-dipole forces? How do typical dipole-dipole forces differ from hydrogen bonding interactions? In what ways are they similar? What are London dispersion forces? How do typical London dispersion forces differ from dipole-dipole forces? In what ways are they similar? Describe the relationship between molecular size and strength of London dispersion forces.

Give an example of such an instance.arrow_forward
- On a particular summer day, the temperature is 30.0C and the relative humidity is 80.0% (which means that the partial pressure of water vapor in the ambient air is 80.0% of the equilibrium vapor pressure of water). A sample of this air is placed in a 1.00-L flask, which is then closed and cooled to 5.0C. What is the mass (in grams) of water that still exists as vapor in the flask? How much liquid water (in grams) condenses out?arrow_forwardThe heats of vaporization of liquid O2, liquid Ne, and liquid methanol, CH3OH, are 6.8 kJ/moL 1.8 kJ/mol, and 34.5 kJ/mol, respectively.
