This question has multiple parts. Work all the parts to get the most points. The Gibbs Free Energy equation is given by the equation: AG = AH - TAS Where: AG = Gibbs Free Energy change AH = Enthalpy change T = temperature AS = Entropy change In order to solve for the temperature, T, in two steps you must: Step One Add the same expression to each side of the equation to leave the term that includes the variable by itself on the right-hand side of the expression: (Be sure that the answer field changes from light yellow to dark yellow before releasing your answer.) +AG = +AH - TAS Drag and drop your selection from the following list to complete the answer: 1 1 -ΔΗ ΔΗ AH AH
