What is the role of disorder in a spontaneous reaction?
gpt
Systems tend to reach a state of higher disorder, measured in entropy, and represented by symbol S. When a system achieves greater disorder, its entropy increases.
Explanation: According to the second law of thermodynamics, a spontaneous reaction is one that tends to increase the disorder or entropy of a system, leading to a state of higher disorder and potentially making the reaction occur spontaneously. This increase in disorder drives the reaction towards equilibrium.
