Understanding Gas Diffusivity
Gas diffusivity refers to the ability of a gas to spread out and mix with other gases. It is a crucial parameter in various chemical engineering processes, including reaction kinetics, separation processes, and environmental engineering.
Typical Values of Diffusivity
The diffusivity of permanent gases typically varies within specific orders of magnitude. For most permanent gases, the diffusivity values can be categorized as follows:
Why is Option D Correct?
The correct answer is option 'D' (10-10 sq.m/s) because:
Conclusion
In summary, understanding the diffusivity of gases is essential for chemical engineers to optimize processes. The typical order for permanent gases being around 10-10 sq.m/s highlights the fundamental characteristics of gas behavior in various applications.

Typical Values of Diffusivity
The diffusivity of permanent gases typically varies within specific orders of magnitude. For most permanent gases, the diffusivity values can be categorized as follows:
- Option a: 10-7 sq.m/s
- Option b: 10-8 sq.m/s
- Option c: 10-9 sq.m/s
- Option d: 10-10 sq.m/s
Why is Option D Correct?
The correct answer is option 'D' (10-10 sq.m/s) because:
- Magnitude of Diffusivity: Permanent gases, such as nitrogen, oxygen, and argon, typically exhibit diffusivity values on the order of 10-10 sq.m/s. This reflects their relatively low molecular weights and sizes.
- Impact of Conditions: Diffusivity can be influenced by temperature and pressure. At standard conditions, the values align closely with the 10-10 range.
- Comparison with Other Gases: Lighter gases may have higher diffusivity, while heavier or more complex gases usually have lower values, often falling below this order.
Conclusion
In summary, understanding the diffusivity of gases is essential for chemical engineers to optimize processes. The typical order for permanent gases being around 10-10 sq.m/s highlights the fundamental characteristics of gas behavior in various applications.
