Q.1.
In a spontaneous process, the entropy of the universe decreases.
Q.2.
Entropy of a system increases when a reaction increases the number of particles.
Q.3.
Entropy of a system decreases when mixing occurs.
Q.4.
Entropy of a system increases when it undergoes a change of state.
Q.5.
Entropy of a system increases when it gains energy.
Q.6.
For a chemical reaction to be feasible, the total entropy change must be zero. (∆Ssystem + ∆Ssurroundings = 0)
Q.7.
The more widely spread out energy is among available energy levels and particles, the less probable that state.
Q.8.
Entropy is a measure of the number of ways in which energy is distributed.
Q.9.
Entropy is a form of energy
Q.10.
A reaction that absorbs energy is
