The mean free path of nitrogen molecules at 27°C is 3 x 10^-7 m/s. If the average speed of nitrogen molecules at the same temperature is 600 m/s then the collision frequency will be?

10^-9/sec

1.5 x 10^-9/sec

2 x 10^-9/sec

3 x 10^-9/sec

Explanation

The collision frequency is 2 × 10^9 collisions per second, which can also be expressed as 2 x 10^-9/sec.
