Scientific Basis of the Calculator
The Collision Frequency Calculator implements the kinetic theory formula:
- Collision Frequency: Z = √2 π d² N ⟨v⟩, where d is the molecular diameter (m), N is the number density (m⁻³), and ⟨v⟩ is the average molecular speed (m/s).
- Number Density: N = P / (k T), where P is pressure (Pa), T is temperature (K), and k is Boltzmann’s constant (1.380649e-23 J/K).
- Average Speed: ⟨v⟩ = √(8 k T / (π m)), where m is the molecular mass (kg).
These formulas, formalized in texts like "Introduction to Thermal Physics" by Schroeder, ensure accurate calculations. For example, for Nitrogen at P = 101325 Pa, T = 300 K, the calculator computes Z ≈ 5e9 s⁻¹. The tool adheres to peer-reviewed standards.
