What does a negative change in entropy indicate?A.The system has become more random.B.The energy of the system has increased.C.The entropy of the system has increased.D.The system has become more ordered.

What does a change in the entropy of a system indicate?A.That the activation energy has changedB.That the disorder of the system has changedC.That the energy of the system has changedD.That the equilibrium position has changed

If the number of particles in a system decreases (while keeping the temperature and phase constant), how does the entropy generally change?Select one:a.The entropy becomes negative.b.The entropy decreases.c.The entropy remains unchanged.d.The entropy increases.

Which of the following is NOT TRUE about predicting the entropy change of the system?*If the reaction produces more gas molecules than it consumes, ΔS° is positive.If the total number of gas molecules diminishes, ΔS° is negative.If the universe's entropy increases spontaneously and remains unchanged in an equilibrium process.If there is no net change in the total number of gas molecules, ΔS° may be positive or negative but will be relatively small numerically.
