Which of the following statement(s) is/are true regarding free energy? (Select all that apply.) A process (at constant T and P) is spontaneous in the direction in which the free energy increases. O If AH and AS favor opposite processes, spontaneity will depend on temperature in such a way that the exothermic direction will be favored at low temperatures. O Solid H20 and liquid H2O have the same free energy at 0°C ( AG° = Gliquid - Gaolid). O -AG means +ASuniv (at constant T and P). O Two functions can be used to predict spontaneity: the entropy of the system and free energy (at constant T and P). O None of the above statements is true.

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 A B с observations Crystallization of a pure compound is spontaneous only below 23. °C. This reaction is spontaneous only above 31. °C but proceeds at a faster rate above 83. °C. The reverse of this reaction is always spontaneous but proceeds faster at temperatures above 108. °C.
