Document Summary
Chem 1 c if both numbers r the same (i. e. one mole vs one mole) changing pressure/volume does nothing to the equilibrium position adding pressure w/other gasses does nothing temperature changes. Free energy and equilibrium change in free energy = -(8. 31j/molk)(temp)(lnk) change in free energy = change in enthalpy - (temperature)(change in entropy) those two equations combined makes von"t hoff exn. Log of the hydrogen ion concentration o: acid o, base o ph = -log[h3o+] = -log[h+] poh = -log[oh-] ph + poh = 14 ph = 6. 99- [h+] > 10^-7 denotes a photon or electron pair has a conjugate base ph = 7. 01+ [h+] < 10^-7 accepts a photon or electron pair has a conjugate acid. H3o+ is the strongest acid that can exist in an aqueous solution. Oh- is the strongest base that can exist in an aqueous solution o neutral o. Kw = [h+][oh-] = [h3o+][oh-] = 10^-14.
