What is the relationship between entropy and spontaneity of a process?

Correct Answer: Higher entropy indicates spontaneity.

Step 1: Understand what entropy is. Entropy is a measure of disorder or randomness in a system.
Step 2: Recognize that spontaneous processes are those that occur naturally without needing external energy.
Step 3: Note that spontaneous processes often lead to an increase in entropy, meaning they create more disorder.
Step 4: Realize that when a process increases the total entropy of the system and surroundings, it is more likely to be spontaneous.
Step 5: Conclude that a higher entropy usually means a process is spontaneous because it reflects a natural tendency towards greater disorder.
