To calculate the free energy (delta G^0,) of a reaction, you can subtract the free energies of formation (G_f^0) of the reactants from those of the products. Given the following data, what will be true of this reaction? C_6H_12O_6 + O_2 rightarrow CO_2 + H_2O G_f^0: -917.30 -394.4 -237.2 The reaction will not require a catalyst to proceed. The reaction is not balanced, so you cannot calculate the change in free energy. The reaction will be endergonic. The reaction will...

Question 5 The spontaneity of a reaction depends both on the enthalpy change, Delta H, and entropy change, Delta S. Reactions that release energy produce more stable products, and the universe tends toward disorder. Thus, an exothermic reaction with a positive entropy change will always be spontaneous. Mathematically, this relationship can be represented as where Delta G is the change in Gibbs free energy and T is the Kelvin temperature. If Delta G is negative, then the reaction is spontaneous....
