Entropy and Gibbs Energy Day 1 Sections 13.1-13.3 1. Are all spontaneous (thermodynamically favorable) reactions exothermic? 2. What is entropy? What is its symbol? 3. Is entropy a state function? 4. What does positive entropy signify? 5. According to figure 13.1, what occurs to the distribution of the kinetic energy of molecules as the system goes from T1 to T2? 6. According to figure 13.1, what occurs to the amount of molecules that have kinetic energy greater than the second mark on the x-axis as the system goes from T1 to T2? 7. Justify how the second law of thermodynamics can be true if you are able to clean up your room. 8. What are the three generalizations that can help decide when a chemical reaction leads to an increase in the disorder of a system? Answer questions 6 and 8 on page 632. On question 8 state whether the entropy should increase (+), decrease (-), or remain the same (0) - this is a change in the directions.
