Viscosity is the internal resistance to the flow possessed by a liquid. The internal resistance depends upon the intermolecular attractive forces. Liquids which flow rapidly have low internal resistance, small intermolecular forces and low viscosity. Glass is an extremely viscous liquid, hence, its properties resemble to that of solids.
Assertion: Effusion rate of Oxygen is smaller than nitrogen.

Assertion: Effusion rate of Oxygen is smaller than nitrogen.
Reason: Molecular size of Nitrogen is smaller than Oxygen.
The correct answer is option C, which states that assertion A is true but reason R is false.
Explanation:
Assertion: Effusion rate of Oxygen is smaller than nitrogen.
Reason: Molecular size of Nitrogen is smaller than Oxygen.
To understand the assertion and reason, let's first discuss the concepts of effusion rate and molecular size.
Effusion Rate:
Effusion is the process by which a gas escapes from a container through a small hole. The effusion rate is the rate at which a gas escapes from the container. It depends on the average velocity of the gas molecules.
Molecular Size:
Molecular size refers to the size of individual molecules. It is determined by the number and arrangement of atoms in a molecule.
Now, let's analyze the assertion and reason:
- Assertion: Effusion rate of Oxygen is smaller than nitrogen.
This statement is true. The effusion rate is inversely proportional to the square root of the molar mass of the gas. Oxygen has a higher molar mass than nitrogen, so its effusion rate is smaller.
- Reason: Molecular size of Nitrogen is smaller than Oxygen.
This statement is false. The molecular size of a gas is not solely determined by its molar mass. Other factors such as the number and arrangement of atoms in a molecule also contribute to molecular size. While nitrogen has a smaller molar mass than oxygen, it does not necessarily mean that its molecular size is smaller.
Conclusion:
The effusion rate of oxygen is indeed smaller than nitrogen, but it is not solely due to the molecular size of nitrogen being smaller than oxygen. Therefore, assertion A is true, but reason R is false.
Reason: Molecular size of Nitrogen is smaller than Oxygen.
The correct answer is option C, which states that assertion A is true but reason R is false.
