Vapour pressure of CCl4 at 25 degree Celsius is 143mm Hg. 0.5g of a non volatile solute ( mol wt.=65) is dissolved in 100ml CCl4. find the vapour pressure of the solution (density of CCl4 =1.58g/cm3) ?

Since, only 0.5 g solute is dissolved in 100 g solvent. Thus the solution is very very dilute. So, the above equation will be modified as: 
FAQs on Vapour-Pressure - Class - 12 Science - Class 12
| 1. What is vapour pressure? |  |
Ans. Vapour pressure is the pressure exerted by the vapour phase of a substance when it is in equilibrium with its liquid or solid phase at a particular temperature. It is a measure of the tendency of a substance to evaporate and is influenced by factors such as temperature, intermolecular forces, and the nature of the substance.
| 2. How is vapour pressure related to temperature? | |
Ans. Vapour pressure is directly proportional to temperature. As the temperature increases, the kinetic energy of the molecules also increases, leading to an increase in the number of molecules with sufficient energy to escape from the liquid or solid phase and form vapour. This results in an increase in vapour pressure.
| 3. What factors affect the vapour pressure of a substance? | |
Ans. The vapour pressure of a substance is influenced by several factors. These include the nature of the substance (such as its molecular weight and intermolecular forces), temperature, and the presence of impurities. Generally, substances with weaker intermolecular forces and lower molecular weights have higher vapour pressures.
| 4. How is vapour pressure used in practical applications? | |
Ans. Vapour pressure is utilized in various practical applications. It is used in industries such as distillation, where the separation of different components of a mixture is based on their different vapour pressures. Vapour pressure is also important in determining the boiling points of liquids and in the design of pressure cookers that cook food faster by increasing the vapour pressure inside.
| 5. How does vapour pressure affect the process of evaporation? | |
Ans. Vapour pressure plays a crucial role in the process of evaporation. When the vapour pressure of a liquid becomes equal to the atmospheric pressure, the liquid starts evaporating at a faster rate. Higher vapour pressure leads to faster evaporation, as more molecules have sufficient energy to escape from the liquid phase and enter the vapour phase.
