NH ₃ and HCl gas are introduced simultaneously from the two ends of a long tube. A white ring of NH ₄ Cl appears first
Options
- Anearer to the HCl end
- Bat the centre of the tube
- Cthroughout the tube
- Dnearer to the NH ₃ end
Correct answer
A. nearer to the HCl end
Step-by-step solution
Distance travelled by gas is directly proportional to rate of diffusion aligned & r_ NH ₃ (l₁ ) 1 M_ NH ₃ 1 17 & r_ HCl (l₂ ) 1 M_ HCl 1 365 & r_ NH ₃ >r_ HCl aligned Length travelled by NH ₃ is greater than HCl . Hence, white ring of NH ₄ Cl is formed nearer to HCl end.
