In gas: Mean-free path and collision rate
…to estimate the number of collisions such a typical diffusing molecule experienced (N) and the average distance traveled between collisions (l), called the mean free path. The product of N and l must equal the total distance traveled—i.e., Nl = 5 × 10⁸ cm. This distance can be thought of…
