ness. 5. The second law of Thermodynamics states that for any spontaneous process, there is a net increase in the total entropy of the system and its surroundings. 6. The second law of thermodynamics explains the relationship between entalpy change and spontaneity of a process. 7. Free energy is a portion of the total energy of a system that is not available to do useful work.

TRUE OR FALSE 

NUMBER 5 TO 7 ONLY

I. Modified True or False Directions: Write CHEMISTRY if the statement is correct, if otherwise, change the underlined words to make the statement correct. 1. The entropy of the universe is always positive as it continues to expand. 2. Entropy is the ability of randomness. 3. A spontaneous process occurs naturally without the action of internal forces. 4. Positive entropy change means a decrease in randomness. 5. The second law of Thermodynamics states that for any spontaneous process, there is a net increase in the total entropy of the system and its surroundings. 6. The second law of thermodynamics explains the relationship between entalpy change and spontaneity of a process. 7. Free energy is a portion of the total energy of a system that is not available to do useful work. 8. Gibbs free energy also determines the non-spontaneity of a reaction 9. According to Gibbs free energy, AH must be positive, while AS is negative. 10. A reversible chemical reaction reaches a state of equilibrium.
