The enthalpy Δ Η ° graphically should be determined given ionization ( K W ) values. Concept Information: Enthalpy changes: The changes in enthalpy that accompanies the formation of one mole of the compound at its normal state from its constituent elements in their standard state. Kw: The self-ionization of water (also autoionization of water, and auto dissociation of water) is an ionization reaction in pure water or in an aqueous solution, in which a water molecule, H 2 O , deprotonates (loses the nucleus of one of its hydrogen atoms) to become a hydroxide ion, O H − . Equilibrium process: When the concentration of the reactants and products remains constant with time the process is said to be at equilibrium. Van’t Hoff Equation: The van’t Hoff equation can be used to estimate K c ( o r ) K p at given temperature provided that K c or K p are known at some other temperature. ln K w = − Δ Η ° R T + C The ( T 1 a n d T 2 ) is the temperature units of (K) and Δ Η is the enthalpy of reaction.
