Solution

The correct option is A True
An ideal solution of two liquids, each component obey Raoult's law; which states that the partial vapor pressure of each component is proportional to its mole fraction. An ideal solution shows thermodynamic mixing characteristics identical to those of ideal gas mixtures. Ideal solutions have intermolecular interactions equal to those of the pure components.

Q. CASE 1: Read the passage given below and answer the following question

The solution which obeys Raoult’s law over the entire range of concentration are known as ideal solutions. The solution which does not obey Raoults law over the entire range of concentration, then it is called non-ideal solution. The vapour pressure of such as a solution is either higher or lower than that predicted by Raoult’s law. If it is higher, the solution exhibits positive deviation and if it is lower, it exhibits negative deviation from Raoult’s law.
