Question 13In terms of energy and entropy, systems tend to change towardA higher energy and lower entropyB higher energy and higher entropyC lower energy and lower entropyD lower energy and higher entropy

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

True or False:1. Entropy is a measure of the number of possible ways that the energy of a systemcan be distributed.2. The second law of thermodynamics states that entropy is always decreasing.3. Gaseous state of matter has the greatest motion and least orderly arrangement.4. The internal energy is often called chemical energy because it is the result of all themotion of the particles and the forces between them.5. For a given chemical reaction, if there is no work done on or by the reaction, thenthere must be a change in volume.6. Entropy is a statistical measure of heat of a system.7. If a chemical reaction is spontaneous, the total entropy of the chemical system andits surroundings increases only if the reaction is endothermic.8. The preferred direction in nature is toward maximum entropy.9. The two forces that drive chemical change are enthalpy and entropy.10. If ΔS is calculated to be positive, there is greater disorder in the products, whichwould drive the reaction in the forward direction.

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.

Which of the following statements is consistent with the second law of thermodynamics?Question 10Select one:a.A gain of free energy in a system is never associated with conversion of energy from one form to another.b.Without an input of energy, the entropy of an organism would tend to decrease over time.c.Every energy transformation performed by an organism decreases the entropy of the universe.d.A constant input of energy is required to maintain the high level of organisation associated with living cells.

Directions: Select the choice that best fits each statement. The following question(s) refer to the following concepts related to energy(A) Heat flow(B) Kinetic energy(C) Potential energy(D) First law of thermodynamics(E) Second law of thermodynamicsQuestionAn energy transformation occurs and results in increased disorder.
