WebC2H6(g) H2(g) + C2H4(g) Answer: ΔG° = 102.0 kJ/mol; the reaction is nonspontaneous ( not spontaneous) at 25 °C. The standard free energy change for a reaction may also be calculated from standard free energy of formation ΔGf° values of the reactants and products involved in the reaction. The standard free energy of formation is the free ... WebApr 9, 2024 · In this paper, the thermodynamic properties of the PbO-ZnO-FeO-Fe2O3-SiO2-CaO six-component slag system were studied by using the molecular-ion coexistence theory, and the influence of slag composition changes on the activity of each structural unit was analyzed. The results show that the calculated value of the activity model is in good …
