States of Matter - Result Question 33
####33. A bottle of dry ammonia and a bottle of dry hydrogen chloride connected through a long tube are opened simultaneously at both ends the white ammonium chloride ring first formed will be
$(1988,1 M)$
(a) at the centre of the tube
(b) near the hydrogen chloride bottle
(c) near the ammonia bottle
(d) throughout the length of the tube
Show Answer
Solution:
- $HCl$ will diffuse at slower rate than ammonia because rate of effusion $\propto \frac{1}{\sqrt{M}}$.
Therefore, ammonia will travel more distance than $HCl$ in the same time interval and the two gas will first meet nearer to $HCl$ end.
