Delta Srxn = (sum VpSp) - (sum VrSr) here v is the coefficient of the compound in the reaction. Delta Hrxn = (sum VpHp) – (sum VrHr) at boiling point dG0 = dH0 – sTS0 = 0 for many non polar liquids (ex. Octane - C8H18, benzene – C6H6) dS = 87J/molK Trutons Law dH0vap = (Tbp) (87 J/molK) T is in units of K
