Find the mean free path and collision frequency of a hydrogen molecule in a cylinder containing hydrogen at 3atm and temperature `27^(@)C`. Take the radius of a hydrogten molecule to be `1overset(0)A`. Given, one atmospheric pressure `=1.013xx10^(5)N m^(-2)` and molecular mass of hydrogen=2.A. `7.66xx10^(-8)m, 2.52xx10^(5)s^(-1)`B. `7.66xx10^(-5)m,2.52xx10^(5)s^(-1)`C. `7.66xx10^(-8)m,2.52xx10^(10)`D. `7.66xx10^(-10)m, 2.52xx10^(8)s^(-1)` |
