What is the significance of 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) --...

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...

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

Here's the problem: A chemical reaction at 1.0 bar and 298 K has ΔrG° = -335 kJ/mol. The Gibbs function of the reactants changes by +7.5 kJ/mol when the pressure is changed from 1.0 bar to some other pressure P2. The products change by +8....

when it says that a particular energy-rich phosphate group requires for example -17 delta-G and another one requires -40 delta-G which one has more energy in it of the two? i.e which one would produce more energy when it gets hydrolysed? thank you in...
