Choose the statement below related to entropy that is correct. Group of answer choicesHeating always decreases the entropy of a system. The solution formation process usually leads to an increase in entropy. The greater number of particles leads to a smaller number of microstates. The reaction that results in an increase in the number of moles of gas always decreases the entropy of a system. An increase in the temperature decreases molecular motions.

The solution formation process usually leads to an increase in entropy

Explanation:

The formation of a solution disperses species such as; molecules, atoms, or ions of one kind throughout the solvent, this generally increases the disorder and results in an increase in the entropy of the system.

Hence dissolution of a solute in a solvent will lead to an increase in the number of particles present in the system. Once the number of particles present is increased, the degree of disorderliness (entropy) of the system is also increased.
