Which process is expected to have an increase in entropy?
olganol [36]

Answer: Option (B) is the correct answer.

Explanation:

Degree of randomness of the molecules of a substance is known as entropy. More is the kinetic energy between the molecules of a substance more will be the degree of randomness.

Therefore, when a substance is present in a gaseous state then it has the maximum entropy. In liquid state, molecules are closer to each other so, there is less randomness between them.

On the other hand, in solid state molecules are much more closer to each other as they arr held by strong intermolecular forces of attraction. Therefore, they have very less entropy.

  • When liquid water is formed from gaseous hydrogen and oxygen molecules then gas is changing into liquid. So, there is decrease in entropy.
  • When N_{2}O_{4} decomposes then the reaction will be as follows.

            N_{2}O_{4} \rightarrow 2NO_{2}

Since, 1 mole is producing 2 moles. This means that degree of randomness is increasing as both the molecules are present in gaseous form.

  • In formation of a precipitate, aqueous solution is changing into solid state. Hence, degree of randomness is decreasing.
  • Rusting of iron also leads to the formation of solid as it forms Fe_{2}O_{3}.xH_{2}O.

Thus, we can conclude that decomposition of N_{2}O_{4} gas to NO_{2} gas is the process that is expected to have an increase in entropy.

Give an example of how you could test Charles Law?
Assoli18 [71]

Explanation:

The experiment is performed at a constant atmospheric pressure. The experiment proceeds by placing an empty flask in a boiling water bath. As the temperature increases, the air inside the flask expands. Afterwards, the gas is cooled in a water bath by maintaining the amount of the air in the flask constant.
