Author Leman 20 Mar 2024

20 Entropy And Free Energy Worksheet Answers - Explain your reasoning in each case. A reaction is spontaneous when δg° < 0 and is nonspontaneous when δg° > 0 gibb's free energy can be calculated from enthalpy change (δh) and entropy change (δs, randomness or degree of disorder). Define entropy in your own words, and list the variables or conditions that you must consider when comparing the entropy of two substances, or when trying to determine the relative change in entropy.
