and it outlines the thermodynamic process for the amount of energy that is required to convert water to hydrogen and Oxygen but that's only at stp The question I have is how do you caclulate the energy requirements if you have different temps and pressures.

I am looking up thermo tables and I get a enthapy for water at various pressures and temps but the problem I am having is finding the entropy of H2 and O2 at the same temps and pressures all i can find is STP entropy. Is there an way to find the values instead of doing the intergration of Dq/T.

And is caclulating the the gibs free energy the best way to see how much work is required to split water
