### Table 16.1: Collisional Parameters for Various Gases This table presents important collisional parameters for a variety of gases. The parameters include the effective hard-sphere radius (\(r\)) and the collisional cross-section area (\(\sigma\)). These values are essential in the study of gas dynamics and molecular collisions, key topics in physics and chemistry. | **Species** | \( r \) (nm) | \( \sigma \) (nm\(^2\)) | |-------------|---------------|------------------------| | He | 0.13 | 0.21 | | Ne | 0.14 | 0.24 | | Ar | 0.17 | 0.36 | | Kr | 0.20 | 0.52 | | N\(_2\) | 0.19 | 0.43 | | O\(_2\) | 0.18 | 0.40 | | CO\(_2\) | 0.20 | 0.52 | #### Description: - **Species**: Refers to the type of gas molecule. - **\( r \) (nm)**: The effective hard-sphere radius, measured in nanometers (nm), which indicates the approximate size of the gas molecule. - **\( \sigma \) (nm\(^2\))**: The collisional cross-section, measured in square nanometers (nm\(^2\)), representing the effective area for collisions between gas molecules. This table will be particularly useful for students and researchers working on gas phase kinetics, allowing for better understanding and calculation of molecular interactions in different gases.
