I have a reaction in a conversion reactor in HYSYS. On paper, I can user the formation enthalpies to calculate the heat of reaction at standard condition. But my reaction is now happening at a much higher temperature, and I need to know how to get the heat of reaction now that temperature and pressure are different from standard conditions.
The equation is water electrolysis reaction:
H2O(g) → H2(g) + 1/2 O2(g)
