What is true about reaction spontaneity and entropy?

The rusting of iron is a nonspontaneous process because rust particles have less entropy than iron, and reactions with a decrease in entropy are nonspontaneous.

A spray of perfume diffusing in a room is a spontaneous process because gas particles have higher entropy when they are spread evenly around the room.

Answer: A spray of perfume diffusing in a room is a spontaneous process because gas particles have higher entropy when they are spread evenly around the room.

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

Spontaneous reactions are those reactions which takes place on their own and do not require any external energy source. Spontaneous reactions are always accompanied by an increse in entropy.

Thus a spray of perfume diffusing in a room is a spontaneous process because gas particles have higher entropy when they are spread evenly around the room.
