Assertion : Molarity of a solution in liquid state changes with temperature.
Reason : The volume of a solution changes with change in temperature.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion : Molarity of a solution in liquid state changes with temperature.
Reason : The volume of a solution changes with change in temperature.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion : If a liquid solute more volatile than the solvent is added to the solvent, the vapour pressure of the solution may increase i.e., ps > po.
Reason : In the presence of a more volatile liquid solute, only the solute will form the vapours and solvent will not.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion (A): Molarity of 0.1 N solution of HCl is 0.1 M.
Reason (R): Normality and molarity of a solution are always equal.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion : If one component of a solution obeys Raoult’s law over a certain range of composition, the other component will not obey Henry’s law in that range.
Reason : Raoult’s law is a special case of Henry’s law.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion : Azeotropic mixtures are formed only by non-ideal solutions and they may have boiling points either greater than both the components or less than both the components.
Reason : The composition of the vapour phase is same as that of the liquid phase of an azeotropic mixture.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion (A): Molarity of a solution in liquid state changes with temperature.
Reason (R): The volume of a solution changes with change in temperature.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion : When methyl alcohol is added to water, boiling point of water increases.
Reason : When a volatile solute is added to a volatile solvent elevation in boiling point is observed.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion (A): An ideal solution obeys Henry’s law.
Reason (R): In an ideal solution, solute-solute as well as solvent-solvent interactions are similar to solute solvent interaction.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion : When NaCl is added to water a depression in freezing point is observed.
Reason : The lowering of vapour pressure of a solution causes depression in the freezing point.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion (A): Dimethyl ether is less volatile than ethyl alcohol.
Reason (R): Dimethyl ether has greater vapour pressure than ethyl alcohol.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion : When a solution is separated from the pure solvent by a semi- permeable membrane, the solvent molecules pass through it from pure solvent side to the solution side
Reason : Diffusion of solvent occurs from a region of high concentration solution to a region of low concentration solution.

Directions: This questions consist of two statements, each printed as Assertion and Reason. While answering this questions, you are required to choose any one of the following four responses.

Assertion (A): Vapour pressure increase with increase in temperature.
Reason (R): With increase in temperature, more molecules of the liquid can go into vapour phase.

Directions: These questions consist of two statements, each printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses.

Assertion (A): Elevation in boiling point is a colligative property.
Reason (R): Boiling point elevation in a dilute solution is directly proportional to the molar concentration of the solute in a given solvent and is independent of the nature of the solute.
