An ideal gas is enclosed in a cylinder at pressure of 2 atm and temperature, 300 K. The mean time between two successive collisions is 6 × 10–8 s. If the pressure is doubled and temperature is increased to 500 K, the mean time between two successive collisions will be close to:

(a)

4 × 10−8s

(b)

3 × 10−6s

(c)

2 × 10−7s

(d)

0.5 × 10−8s
