Solution
-
True: Entropy is indeed a measure of the number of possible ways that the energy of a system can be distributed.
-
False: The second law of thermodynamics states that entropy is always increasing, not decreasing.
-
True: The gaseous state of matter does have the greatest motion and least orderly arrangement.
-
False: The internal energy is not often called chemical energy. It is a form of energy but it is not specifically the result of all the motion of the particles and the forces between them.
-
False: For a given chemical reaction, if there is no work done on or by the reaction, it does not necessarily mean there must be a change in volume.
-
False: Entropy is not a statistical measure of heat of a system. It is a measure of disorder or randomness.
-
False: If a chemical reaction is spontaneous, the total entropy of the chemical system and its surroundings increases regardless of whether the reaction is endothermic or exothermic.
-
True: The preferred direction in nature is indeed toward maximum entropy.
-
True: The two forces that drive chemical change are indeed enthalpy and entropy.
-
True: If ΔS is calculated to be positive, there is greater disorder in the products, which would drive the reaction in the forward direction.
