Question

ammonia and hydrogen chloride gases are released from the two opposite corners in a room. which gas will reach first to a person sitting in the center of the room. Please give me the explanation too.

Answer 1

Rate of diffusion is inversely proportional to the root of the molecular masses of the compound.

Therfore larger the molecular mass lesser would be the rate and hence would reach slowly.

Therfore NH3 would reach first as compare to the HCl being lighter one.
