Thus larger the molecular mass, smaller would be the rate of diffusion.
∴, NH

being light will reach first as compared to HCl being lighter one.
Answer:
Explanation:
The reaction which is taking place is:
ammonia + hydrogen chloride → ammonium chloride
NH3 (g) + HCl (g) → NH4Cl (s)
It typically takes just a few minutes for the ring to form, but the exact time will depend on the dimensions of the tube, the amount of the solutions which are put on the cotton wool wads and the temperature of the room.
The ring usually forms nearer to the hydrochloric acid end of the tube because hydrogen chloride diffuses more slowly than ammonia. This is because hydrogen chloride has almost twice the molecular weight of ammonia, and the rate of diffusion is inversely proportional to the square root of the molecular mass of the gas.
It is worth noting that the rate of diffusion is not the same as the speed at which the gas molecules travel (which is hundreds of meters per second). The gas molecules follow a zig-zag path through the tube as they collide with the air molecules in the tube.
The purpose of the glass tube is to eliminate air currents and to see if the gas molecules will move on their own.
