If the system becomes more disordered, the entropy change will be positive. If the system becomes more ordered, the entropy change will be negative.
entropy is decreasing, so negative
negative
The changes in enthalpy, entropy, and free energy are negative for the freezing of water since energy is released as heat during the process. At lower temperatures, the freezing of water is more spontaneous as the negative change in enthalpy dominates over the positive change in entropy, making the overall change in free energy negative and leading to a spontaneous process.
When water freezes, the change in entropy is negative. This is because in the process of freezing, the molecules become more ordered and arranged into a crystalline structure, leading to a decrease in randomness and disorder in the system. This decrease in disorder corresponds to a decrease in entropy.
If the system becomes more disordered, the entropy change will be positive. If the system becomes more ordered, the entropy change will be negative.

Entropy is always a non-negative quantity according to the Second Law of Thermodynamics, meaning it cannot be negative. Entropy change can be negative for a system that is undergoing a process that decreases its disorder, while entropy production refers to the total increase in entropy within a system and its surroundings, which is always positive or zero but cannot be negative.

G is always positive when enthalpy increases and entropy decreases.
Negative entropy is a process or chemical reaction proceeds spontaneously in the forward direction.Positive entropy is a process proceeds spontaneously in reverse.
When sugar dissolves in water, the change in entropy is generally positive. This is because the sugar molecules become more dispersed in the solvent, increasing the disorder or randomness of the system.
The reaction N2 (g) + 3H2 (g) → 2NH3 (g) shows an increase in entropy because it involves an increase in the number of gaseous molecules from 2 to 4. Therefore, the entropy change for this reaction is positive.
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
