The diameter of a nitrogen molecule is about 0.29 nm.In a tank of nitrogen at a pressure of 2.5 atm and temperature 273 K,what is the mean free path of a nitrogen molecule?
A) 39 nm
B) 56 nm
C) 177 nm
D) 125 nm

Question

Quizplus · Accepted Answer

The mean free path (λ) can be calculated using the formula: λ = kT / (√2 * π * d² * P), where k is the Boltzmann constant, T is the temperature, d is the diameter of the molecule, and P is the pressure. Substituting the given values, λ ≈ 39 nm.
