KOH(s)--> KOH(aq) DH=-57.6 kJ/mol
When I define KOH(aq) as a component, I supply mol wt, DHf, DGf, density, and melting point. When I run it, it asks for vapor pressure data. I used all kinds of reactor models on ASPEN but get the same error message.
Aspen has KOH, KOH:A, KOH:B, and KOH*W (KOH with one molecule of water of crystalization). I am not sure how to look up what KOH:A and KOH: B are.
My goal is to recover the heat from this reaction. I have manually calculated this using DH but would like to add it to my ASPEN flow sheet.
