Entropy is the heat present in the chemical system with constant pressure. With an increase in the mole number, the entropy change of the reaction increases. Thus, option B is correct.
What is the relation between entropy and moles?
Entropy is thermal energy present in the thermodynamic system that defines the available energy to perform the work and disorderness of the molecules in a reaction. It is also affected by the randomness of the molecules in the system.
The entropy of the reaction is directly dependent on the moles and molarity of the substance. It has been known that an increase in moles of the product raises the entropy whereas fewer moles produced, decrease the entropy.
Therefore, the high number of moles increases the entropy.
