Does pressure affect the thermal breakdown of water?

[QUOTE="trurle, post: 6635154, member: 653393"] Qualitatively, the Le Chatelier`s principle is applicable here. Thermolizing water increase pressure (two water molecules split into one molecule of oxygen and two of hydrogen), therefore increased pressure shift equilibrum back to formation of water. In detail, effect of pressure is affecting the entropy component ΔS of Gibbs energy , while heat component ΔH is unchanged. Therefore, with increased pressure, your energy expended to reach desired decomposition yield should not change if pump is 100% efficient, but termolizis temperature will increase. To calculate temperature of 50% thermolysis yield, your should solve Gibbs free energy equation ΔH-TΔS=0. Of course, in real world 100% efficient pumps do not exist, therefore high pressure thermolysis of water will require more energy compared to ambient pressure thermolysis. [/QUOTE]
