3.Calculate the free energy(ΔG°)of the following reactions:(10 pts)a)H2(g) + O2(g)→ H2O2(g)b)H2O2(g) + H2(g) → 2 H2O (g) How do the free energy values for these two reactions compare to the free energy of the combustion of hydrogen gas? Hint: (ΔG) is a state function, therefore Hess’s law is applicable.The combustion of hydrogen gas is modeled by the overall equation is 2 H2(g) + O2(g)→ 2 H2O(g).
I have no idea how to calculate the free energy, can you please explain this to me step by step.
