Answer:
The change in entropy is negative; -ΔS
Explanation:
The entropy of a system measures the degree of randomness or energy dispersal of the system. The symbol for entropy is S.
For a given system, the change in entropy is symbolized as ΔS.
For an increase in entropy of a system, the final entropy must be greater than the initial entropy i.e. Δfinal > Δinitial. Therefore ΔS > 0
For a decrease in entropy of a system, the final entropy must be less than the initial entropy i.e. Δfinal < Δinitial. Therefore ΔS < 0 or ΔS is negative
A system with decreasing entropy may have a positive or negative free energy change, ΔG.
Also, a system with decreasing entropy may have a positive or negative enthalpy change, ΔH.
