A decrease in entropy typically occurs in processes that involve the organization of matter or energy, such as the formation of ice from water or the crystallization of a substance from a solution. In these cases, particles become more ordered, resulting in a lower entropy state. Additionally, when energy is added to a system in a controlled manner, such as cooling a gas, it can lead to reduced disorder and lower entropy. However, according to the second law of thermodynamics, the total entropy of an isolated system can never decrease; it can only decrease locally at the expense of increasing the overall entropy elsewhere.
The lowest possible entropy occurs in a system at absolute zero temperature. At this point, the system is in a state of maximal order, with all particles at rest and in perfect arrangement, resulting in zero entropy.
An endothermic reaction occur with heat absorption.

The change in enthalpy between products and reactants in a reaction
Guys watch out the question, if your question end with positive then the answer will be An endothermic reaction that decreases in entropy. If the question end with negative then its An exothermic reaction that increases in entropy--APEX hope this help

The change in entropy between products and reactants in a reaction
The lowest possible entropy occurs in a system at absolute zero temperature. At this point, the system is in a state of maximal order, with all particles at rest and in perfect arrangement, resulting in zero entropy.
The entropy increases, as going from a solid to a gas increases disorder or randomness in the system. This is because gases have more freedom of movement and energy compared to solids.
The entropy increases in this reaction, as the solid reactant (I2(s)) is becoming a gas (I2(g)), which represents a higher degree of disorder and randomness on a molecular level. The increased entropy contributes to the spontaneity of the reaction.
