Rate at which gases travel are inversely proportional to their molecular mass,
More the molecular mass, less will be its rate of diffusion.

Rate\ \alpha\  \frac{1}{molar\ mass}

molar mass of HCl = 36.5g
mole mass of NH₃ = 17g

Since NH₃ has lower molecular mass, it will travel faster. The distance travelled by it will also be higher than that of HCl.

are u sure
ammonia also correct right
yes for iodine or ammonia
Yes for iodine. I am not sure about whether ammonia sublimes. Ammonium nitrate is a sublimating substance.
The rate of diffusion of a gas is inversely proportional to the square root of its molar mass. As HCl has a greater molar mass, it will travel at slower speed and NH3 will travel faster.
