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 escape in the time required for one-half of the hydrogen to escape?
Options
- A1 8
- B1 4
- C3 8
- D1 2
Correct answer
A. 1 8
Step-by-step solution
n 1 t 1 n 2 t 2 = M 2 M 1 ⇒ n 2 = 1 2 , n 1 = n ′ ⇒ 2 t 2 n ′ t 1 x 1 = M 2 M 1 = 2 32 = 1 16 = 1 4 Assuming t 2 = t 1 2 n ′ t 2 t 1 = 1 4 ∴ n ′ = 1 8
