QNEET-2016-Ch-1022: NEET 2016 Chemistry - Class 11 NEET-2016-Ch-1022 Solution: Equal moles of hydrogen and oxygen gases are placed in a…
Equal moles of hydrogen and oxygen gases are placed in a container with a pin-hole through which both can escape. What fraction of the oxygen escapes in the time required for one-half of the hydrogen to escape?
Multiple Choice Options
- A 3/8
- B 1/2
- C 1/8
- D 1/4
Step-by-Step Verified Solution
Let the number of moles of each gas = x
Fraction of hydrogen escaped = 1 2 x
r O 2 r H 2 = M H 2 M O 2
_ n O 2 / t x 2 / t = 2 32 = 1 16 = 1 4
_ n O 2 = 1 8 x
Then, fraction of oxygen escaped = 1 8
