Unformatted text preview: ∆G = ∆H – T∆S Old stuff: ∆ E = q + w W = P∆V sign conventions At equilibrium: ∆G = 0 Therefore, ∆H = T∆S Trouton’s rule: 85 J/mol K = ∆S v = ∆H V /T B Solutions Molarity, M = moles/liter Molality, m = moles solute / kg solvent – temperature independent Mass percent: mass solute/total mass of solution * 100 Mole fraction: moles solute / total number of moles PPM: parts per million, mg solute/kg of solution = mg solute / volume in L (true for density = 1.00) Raoult’s law: P Total = X solvent P O solvent Van’t Hoff Equation: ∆T = k*m*I … k=solvent dependent constant, m is molality, i is the van’t hoff factor...
