[QUOTE="chemnoob., post: 2985397, member: 275946"] [h2]Homework Statement [/h2] Calculate the vapour pressure of H2O(g) at 298K and an overall pressure of 1 atm., using the data provided. It cannot be assumed that dHvap and dSvap are independent of temperature. H2(g) dHcomb (298K) = -241.8kj/mol (H2(g) as a product)) Cp - 33.6 H2(g) dHcomb (298K) = -285.8kj/mol (H2(l) as a product)) Cp - 75.3 [h2]Homework Equations[/h2] [h2]The Attempt at a Solution[/h2] I believe I need to calculate deltaH of vaporization first then use dSvap(298) = dSvap(373)+dCpln(298/373) then use gibbs free energy? Don't know how to get deltaH [/QUOTE]
