Vapour pressure of dilute aq. solution of glucose is 750 mm of Hg at 373 K. The mole fraction of the solute is ( p^@ water = 760 mm of Hg)
The vapour pressure of an aqueous solution of glucose is 750 mm of mercury at 100^@ C . Mole fraction of solute will be
The total vapour pressure of a binary solution is gives by P = ( 100X_(A) + 260 X_(B) )mm Hg where, X_(A)and X_(B) are the molefractions of components A and B. This indicates that the:
The lquid A and B from ideal solutions. At 300 K, the vapour pressure of solution containing 1 mole of A and 3 mole of B is 550 mm Hg. At the same tempreature, if one more mole of B is added to this solution, the vapour pressure of the solution increases by 10 mm Hg. determinethe vapour pressure of A and B in their pure states (in mm Hg):
The vapour pressure of the solvent decreased by 10 mm of Hg when a non volatile solute was added to the solvent. The mole fraction of the solute in the solution is 0.2. What should be the fraction of the solvent if a decrease in vapour pressure of 20 mm of Hg is desired:
The vapour pressure of mercury is 0.002 mm Hg at 27^(@)C . K_(c) for the process Hg(l)hArrHg(g) is :
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
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?
The vapour pressure of pure liquids A and B are 450 and 700 mm Hg at 350 K respectively. Find out the composition of the liquid mixture if total vapour pressure is 600 mm Hg. Also find the composition of the vapour phase.
