Question

how we can prove that speed of diffusion of ammonia is more than hydrochloric acid

Answer 1

Heya friend here is your ans

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
