A solution of two liquids boils at a temperature more than the boiling point of either of them. Hence, the binary solution shows

negative deviation from raoult's law

positive deviation from raoult's law

no deviation from raoult's law

positive or negative deviation from raoult's law depending upon the composition.

Text Solution

Verified by Experts

The correct Answer is:

The vapour pressure of the solution is lower than that of either of two liquids. Hence, the solution shows negative deviation from raoult's law.

Read the passage given below and answer the following questions : Raoult's law states that for a solution of volatile liquids, the partial vapour pressure of each component of the solution is directly proportional to its mole fraction present in solution. Dalton's law of partial pressure states that the total pressure P_("total") over the solution phase in the container will be the sum of the partial pressures of the components of the solution and is given as: P_("total") = P_1 + P_2 A solution of two liquids boils at a temperature more than the boiling point of either of them. What type of deviation will be shown by the solution formed in terms of Raoult' s law ?
