Question

1. Is there a relationship between time and distance in movement of ammonia molecules?

2.discuss the relationship with supporting measurements below.

3. Is the diffusion of ammonia molecules randomly timed or defined ?

4. Defend your answer.

Answer 1

1. the movement of molecule is inversely proportional to the square root of its molar mass. So a higher molecular weight molecule would move slower than a low molecular weight molecule. the distance thus travelled would be shorter for higher molecular weight molecule as compared to low molecular weight molecule.

2. The movement and distance relationship is defined by kinetic theory of gases model.

3. The diffusion of ammonia molecule is found to be random and non-directional in nature by experiments.

the rate of diffusion is defined as the distance travelled by the molecule in a given time.
