x ml of H2 effuse through a hole in a container in 5 sec.the time taken for the effusionof same volume of the gas specified below under identical condition is

1.10s,He

2.20s,O

3.25s,CO

4.55s,CO2

i.e 4 x 5s = 20 s

Hence, option 2 is correct

  • -38

If we consider O2 in Option 2, then it is the correct one.
