Question
The Gibbs free energy changes for the reaction 2Au(s)+1.5O2(g)=Au2O3(s). At 25 oC (298K) is 80 J/mole. (a) if the enthalpy change at 298K is -13
The Gibbs free energy changes for the reaction 2Au(s)+1.5O2(g)=Au2O3(s). At 25 oC (298K) is 80 J/mole. (a) if the enthalpy change at 298K is -13 J/mole, estimate the entropy change at 298K. Specify any assumptions used for the estimate. (b) estimate the value of oxygen pressure needed for oxidation of gold
