Question

Two statements are given- one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (i),(ii),(iii) and (iv) as given below. Assertion : The rate of diffusion in liquid is more tan solid , Reason : The inter molecular force of attraction is more in solid than in liquid.

° Both A and R are true and R is correct explanation of the assertion
° Both A and R are true but R is not the correct explanation of the assertion
° A is true but R is false.
° A is false but R is true.

Answer 2

The correct answer to the given question is provided by 1st statement:

Both A and R are true and R is the correct explanation of the assertion.

• Solids are the matter in which the constituents components or the atoms present inside it are packed in such a way to each other that there is no or negligible gap between them.
• This does not provide space for these constituents to move or flow. Hence, constituents of solids cannot diffuse or flow.
• It can be said that these particles are highly attracted to each other.
• Whereas in liquids as compared to solid matter this is the reverse case.
• The particles are not highly attracted, leaving space for them to flow. It is called diffusion or the fluidity of matter.
• Hence, the assertion is true that the rate of diffusion is higher in this matter state.
• The reason statement is also true as attraction force is higher in solids at the atomic level.
• It is the correct explanation of the main statement.
• Hence, assertion, the reason is true with the reason being the correct explanation.
