Answer:
The change in entropy is negative when the disorder in an isolated system decreases and becomes more ordered.
Explanation:
Entropy denotes the amount of disorder present in a system. According to the second law of thermodynamics, everything is normally in a state of positive entropy.
For a spontaneous reaction, entropy change is always positive.However, in order to make a system less disordered, energy is required.
