At room temperature, NH3(g) and HX(g) are passed into a 1m long tube from two opposite ends at the same pressure. The formation of NH4X (s) will be closest from the injection of HX end when HX is
Options:
Answer:
D
Solution:
The white deposit forms where the gases meet; the meeting point is closest to the HX end when HX diffuses slowest relative to NH3, i.e., when HX has the largest molar mass (r ∝ 1/√(M)). HI (M = 128) is the heaviest of HF (20), HCl (36.5), HBr (81). Confirms Ans: (d) HI.
