Correct answer is (a) 4.58 × 109 s-1

Q. Estimate the mean free path and collision frequency of a nitrogen molecule in a cylinder containing nitrogen at 2 atm and temperature $1 7^{0} C$ . Take the radius of a nitrogen molecule to be $1 A^{0}$ . (Molecular mass of nitrogen,= 28u)

$4.58 \times 1 0^{9} s^{- 1}$

$2.5 \times 1 0^{10} s^{- 1}$

$9.1 \times 1 0^{11} s^{- 1}$

$6.2 \times 1 0^{9} s^{- 1}$

Correct answer is (a) $4.58 \times 1 0^{9} s^{- 1}$
