The system has become more ordered.
The system has become more ordered.
Assuming you mean can entropy be reduced; the answer is yes. Only in an open system such as our planet. The universe is a closed systems. The entropy of the universe cannot be reduced. Chemical changes can reduced entropy in an open system. When gas turns into a liquid or when a liquid turns into a solid; entropy is reduced.
An exothermic reaction with a negative entropy change indicates that the reaction releases heat to its surroundings and results in a decrease in disorder or randomness of the system.
For a spontaneous reaction, the change in entropy (delta S) is typically positive.
Changing the temperature
If the system becomes more disordered, the entropy change will be positive. If the system becomes more ordered, the entropy change will be negative.
The system has become more ordered.
entropy is decreasing, so negative
Assuming you mean can entropy be reduced; the answer is yes. Only in an open system such as our planet. The universe is a closed systems. The entropy of the universe cannot be reduced. Chemical changes can reduced entropy in an open system. When gas turns into a liquid or when a liquid turns into a solid; entropy is reduced.
Negative (A+) AG : )

negative
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.
positive
Changing the temperature
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.
