The change in entropy equals zero when a process is reversible, meaning that the system and surroundings return to their original state without any net change in entropy.
The entropy change in a reaction can be calculated by comparing the entropy of the products to the entropy of the reactants. Without specific entropy values provided, it is difficult to determine the exact change. However, in general, the entropy change is positive in reactions where the products have higher entropy than the reactants, indicating an increase in disorder.
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.
Yes, at equilibrium, the standard Gibbs free energy change (G) is equal to zero.
The standard molar entropy of an H+ ion at 25°C is approximately 0 J/mol-K. Since the H+ ion is a single charged particle with no internal degrees of freedom, its entropy is considered to be close to zero.
In an adiabatic process, entropy remains constant.
The change in entropy is zero when a process is reversible, meaning that the system and surroundings return to their original state without any net change in entropy.
Entropy is a measure of disorder in a system and is always equal to or greater than zero according to the second law of thermodynamics. Entropy cannot be negative in a closed system.
At equilibrium, the change in entropy (ΔS) of the system is zero. This means that the system is in a state of maximum entropy where there is no further tendency for change in the system.
The only way to have zero entropy is to have a temperature of absolute zero.
Yes. Isentropic means "constant entropy." For all reversible processes, the change in entropy for the system and its environment is zero.
The entropy of an ideal gas during an isothermal process may change because normally the entropy is a net zero. The change of on isothermal process can produce positive energy.
I don't think entropy can get less than zero

Negative entropy is a process or chemical reaction proceeds spontaneously in the forward direction.Positive entropy is a process proceeds spontaneously in reverse.
There is no accepted or established "fourth law of thermodynamics". There are, however, numerous authors who have postulated versions of fourth laws to explain certain aberrant phenomena. The following link gives over fifteen different versions of postulated "fourth" laws of thermodynamics: http://www.humanthermodynamics.com/4th-Law-Variations.html

At absolute zero temperature, water molecules have no thermal energy to move or vibrate, leading to a highly ordered and structured arrangement. This low energy and high level of order result in minimal entropy, as entropy is a measure of the disorder or randomness in a system.
