This value can vary slightly depending on the temperature and pressure. Here's a breakdown:
* Temperature: The diffusivity coefficient increases with temperature.
* Pressure: The diffusivity coefficient decreases with increasing pressure.
How to find the diffusivity coefficient at different conditions:
You can use the following equation to estimate the diffusivity coefficient at different temperatures and pressures:
```
D(T, P) = D(T_ref, P_ref) * (T/T_ref)^1.75 * (P_ref/P)
```
where:
* D(T, P) is the diffusivity coefficient at temperature T and pressure P.
* D(T_ref, P_ref) is the diffusivity coefficient at the reference temperature T_ref and pressure P_ref (e.g., 0.096 cm²/s at 25°C and 1 atm).
* T is the temperature in Kelvin.
* T_ref is the reference temperature in Kelvin (298.15 K).
* P is the pressure in atm.
* P_ref is the reference pressure in atm (1 atm).
Note:
* This equation is an approximation and may not be accurate for all temperatures and pressures.
* Other factors like humidity and the presence of other gases can also affect the diffusivity coefficient.
For more accurate values, you can consult specialized databases or use more sophisticated models.
