Which of the following solutions will have the lowest vapour pressure
A solution containing 30g of non-volatile solute exactly in 90g of water has a vapour pressure of 2.8" kP"_(a) at 298 K. Further 18g of water is then added to the solution and the new vapur pressure becomes 2.9" kP"_(a) at 298 K. Calculate (i) The moar mass of the solute and (ii) Vapour pressure of water at 298 K.
The vapour pressure of a solution containing non volatile solute is less than the vapour pressure of pure of solvent. Give reason.
Assertion : Vapour pressure of 0.5M sugar solution is more than 0.5M KCl solution Reason: Lowering of vapour pressure is directly proportional to the number of particles present in the solution
A non-volatile solute (A) is dissolved in a volatile solvent (B). The vapour pressure of the resultant solution is P_(s^(*)) . The vapour pressure of pure solvent is P_(B)^(@) . If X_(B) is the mole fraction of the solvent, which of the following is correct?
Two pure liquids A & B which can from ideal solution have vapour pressures 300 torr & 800 torr . A mixture of the vapour of A & B for which the mole fraction of A is 0.25 is slowly compressed at temperature T. The total pressure applied when only last bubble of vapour remains
Two pure liquids A & B which can from ideal solution have vapour pressures 300 torr & 800 torr . A mixture of the vapour of A & B for which the mole fraction of A is 0.25 is slowly compressed at temperature T. The molefraction of B in the last track of vapour is :
