A plot is obtained for two volatile liquids A & B as follows. From the plot answer the following. What is the total pressure of the solution phase?

A plot is obtained for two volatile liquids A & B as follows. From the plot answer the following. Which of the liquids have higher boiling point?

Solution of two volatile liquids A and B obey Roalt's law. At certain temperature, it is found that when the toal pressure above a solution is 0.53 bar. The mol fraction. A in the vapour is 0.45 & other liquid is 0.65. What are the vapour pressures of the two pure liquids at the given temperature?

Samples of four metals A,B,C and D were taken and added to the following solutions one by one.The results obtained have been tabulated as follows. Use the table above to answer the following questions about metals A,B,C and D. (i)Which is the most reactive metal? (ii)What would you observe if B is added to a solution of copper (II) sulpahate? (iii)Arrange the metals A,B,C and D in the order of decreasing reactivity.

Answer the following questions with reference to nitrogen: Two organic compounds in which it is a component.

The vapour pressures fo pure liquids A and B are 450 mm Hg and 700 mm Hg respectively at 350K. If the total vapour pressure of the mixture of the two liquids at 350K is 600mm Hg, Calculate the more fractions of the two components in the solution. Also, calcuate the partial pressures of the two components in the vapour phase.

Two cylinders A and B of equal capacity are connected to each other via a stopcock. A contains a gas at standard temperature and pressure. B is completely evacuated. The entire system is thermally insulated. The stopcock is suddenly opened. Answer the following: What is the change in the temperature of the gas?

With the help of Raoult's law show that total vapour pressure of a binary liquid solution varies linearly with the mole fraction of a component.

100 g of liquid A (molar mass 140 g mol^-1) was dissolved in 1000g of liquid B (molar mass 180 g mol^-1) . The vapour pressure of pure liquid B was found to be 500 torr: Calculate the vapour pressure of pure liquid A and its vapour pressure in the solution if the total vapour pressure of the solution is 475 Torr.

Two cylinders A and B of equal capacity are connected to each other via a stopcock. A contains a gas at standard temperature and pressure. B is completely evacuated. The entire system is thermally insulated. The stopcock is suddenly opened. Answer the following: (a)What is the final pressure of the gas in A and B?
