Consider the reaction  2O(g)=O2(g) a. Predict deltaH and deltaS.  b. Would the reaction be more spontaneous at high or low temperatures?
Which expression below could be used to calculate the free energy change for a chemical reaction at any temperature? Choose one: 1. ΔG°rxn = ΔH°rxn – TΔS°rxn  2. ΔG°rxn = Σ(ΔG°f,Reactants) – Σ(ΔG°f,Products) 3. ΔG°rxn = ΔH°rxn + TΔS°rxn  4. ΔG°rxn = Σ(ΔG°f,Products) – Σ(ΔG°f,Reactants)
For the conversion of reactant A to product B, the change in enthalpy is 7.80 kJ·mol-1 and the change in entropy is 44.4 J·K-1·mol-1. Above what temperature, in Kelvin, does the reaction become spontaneous?___ K.
