What is Gibbs Free Energy?

The reaction CaCO3 (s) CaO (s) + CO2 (g) is endothermic. What will happen to the Gibbs free energy if the temperature increases? A. One cannot predict since S is not known B. It will remain the same C. It will increase D. It will decrease And can you...

E.g. Grand Potential <=> Grand Canonical Ensemble and Helmholtz Free Energy <=> Canonical Ensemble.

Estimate the ΔGo for the following reaction. What is ΔGo at 298 K if p = 0.25 bar for each gaseous substance in the above Reaction. 1) 2 H2(g) + O2(g) ---> 2 H2O(l) 2) C(s, graphite) + 2 H2(g) ---> CH4(g) 1) I used the formula Gibbs free energy...

Calculate Gibbs free energy change in kj for the reaction below at 25C, when the pressures of N2, H2, and NH3 are 2.50 atm, 4.62 atm, and .0305 atm, respectively. (I have the thermodynamic data if needed Just give me steps please!) N2(g) + 3H2(g) --...

Why does a negative value for the change in Gibbs free energy tell us whether or not a process will be spontaneous as written? 1. because the change in Gibbs free energy is directly ...show more

EDIT : I meant the ∆fG° of H+, not the ∆rG°. The reaction is CH2O + 2H2AsO4(as in four oxygen, not four minus)- -- HCO3(three oxygen, not three minus)- + 2H2AsO3(three oxygen, not three minus) + H+ We are given the ∆fG° for each species except H+ and...
