At a certain temperature, the vapour pressure (in mm Hg) of `CH_3OH` and `C_2H_5OH` solution is represented by P=119x+135 where x is the mole fraction of `CH_3OH`. What are the vapour pressures of pure components at this temperture?

Vapour pressure of a solution of heptane and octane is given by the equation: p(sol.)(mm Hg)=35+65x, where x is the mole fraction of heptane. vapour pressure of pure heptane is

An ideal solution was found to have a vapour pressure of 80 torr when the mole fraction of a non-volatile solute was 0.2. What would be the vapour pressure of the pure solvent at the same temperature?

At 20^@C the vapour pressure of pure liquid A is 22 mm Hg and that of pure liquid B is 75mm Hg. What is the composition of the solutions of these two components that has a vapour pressure of 48.5 mm Hg at this temperature?

Vapour pessure of a liquid or a solution is the pressure exerted by the vapour in equilibrium with the liquid or solution at a particular temperature. It depends upon the nature of the liquid and temperature. It depends upon the nature of the liquid and temperature. According to Raoult's law in a solution, the vapour pressure of a component at a given temperature is equal to the mole fraction of that component in solution multiplied by the vapour pressure of that component in hte pue state. this solution in which each component obeys Raoult's law are called ideal solutions. there are two types of non ideal solutions, showing positive deviations and negative deviations from ideal behaviour. If liquid A and B form ideal solution, then

P_A and P_B are the vapour pressure of pure liquid components A and B respectively of an ideal binary solution. If X_A represent the mole fraction of component A, then the total pressure of the solution will be

Two liquids X and Y on mixing form an ideal solution. The vapour pressure of the solution containing 3 mol of X and 1 mole of Y is 550 mm of Hg. But when 4 mol of X and 1 mol of Y are mixed, the vapour pressure of the solution thus, formed is 560 mm of Hg. what will be the vapour pressure of the pure X and pure Y at this temperature?

Two liquid A and B have vapour pressure in the ratio P_A^(@) : P_B^(@) =1.3 at a certain temperature.Assume A and B from an ideal solution and the ratio of mole fractions of A to B in the vapour phase is 4 : 3, then the mole fraction of B in the solution at the same tempreature is :

1.0 gram of a non-volatile solute was dissolved in 100 gram of acetone (molecular mass = 58) at 298 K. The vapour pressure of solution was found to be 192.5 mm of Hg. Calculate the molecular mass of solute. The vapour pressure of pure acetone at 298 K is 195 mm of Hg.
