AThe usable energy available to do work
BThe total bond energy of the products
CThe randomness or disorder within a system
DThe rate at which a system loses heat
Answer & Solution
Correct answer: C. The randomness or disorder within a system
1. Entropy is the measure of randomness or disorder within a system.
2. High entropy means high disorder and low energy.
3. The more energy a system loses to its surroundings, the less ordered and more random that system becomes.
4. Usable energy available to do work is free energy, which is the quantity entropy is subtracted from.
