The answer choices for both diagrams are: no change, negative, or positive. Determine the signs of the changes in entropy, AS, and enthalpy, AH, for the physical changes. Assume a closed or isolated system. -> 8 80 AS AH ASE AH
please include the sign of each for H and S its either positive/negative/unknown O ENTROPY AND FREE ENERGY Using the conditions of spontaneity to deduce the signs Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy AS. Note: If you have not been given enough information to decide a sign, select the "unknown" option reaction observations conclusions AH is pick one This reaction...
