Understanding the Role of Gibbs Free energy and Enthalpy as the energy required to drive a reaction
I was looking at the enthalpy change for water-splitting reaction:
$$ \Delta H^o_R = [\Delta H^0_{H_2(g)} +\frac{1}{2}\Delta H^0_{O_2(g)}]-\Delta H^0_{H_2O(l)} = \pu{285.83 kJ/mol}$$
According to ...

How much energy water "captures" at it evaporates in room temperature?
As explained in Why does water evaporate spontaneously at room temperature despite ΔG > 0? water evaporates in room temperature because partial pressure of water is less than "standard" conditions ...

Discrepancies in calculating free energy values listed in Stumm and Morgan
I am hoping someone can help me with a clarifying a calculation on a fundamental thermodynamic understanding of reactions. Below is Table 2.5 from Stumm and Morgan's Aquatic Chemistry.
Table 2.5. ...

Is water committed to vapor state at boiling point or after? [duplicate]
Quite early into my studies, I learnt about phase changes with this graph.
I’m just going to focus on vaporization/condensation. I learnt that the plateau was caused because all the heat was going ...

Determining standard Gibbs free energy for water?
I am dealing with the dissociation of water into its components hydrogen and oxygen and I am trying to determine the standard Gibbs free energies of each component. My professor said if the substance ...
