A decrease in entropy is associated with which of the following types of reaction?
Answer:
A decrease in entropy is typically associated with exothermic reactions. In exothermic reactions, heat energy is released to the surroundings, resulting in a decrease in entropy. These reactions are characterized by the transfer of energy as heat from the system to the surroundings, leading to a decrease in disorder or randomness within the system. As a result, the products of exothermic reactions often have lower entropy than the reactants. The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time, but within a system or during a reaction, entropy can decrease temporarily as long as the overall entropy change of the universe increases.
