An equilibrium constant of special importance in much aqueous chemistry is that of the autoionization of water: 2 H₂O (/) H3O+ (aq) + OH¯ (aq) Kw The value of this equilibrium constant at three temperatures near standard temperature is Kw(293 K) = 0.67 × 10-¹4 M² Kw(298 K) = 1.00 × 10-¹4 M² Kw(303 K) = 1.45 × 10-¹4 M² (a) Assuming that the value of AH° and AS° are constant over this narrow temperature range, determine their values (in kJ/mol and J/mol-K, respectively for the ionization equilibrium at 298 K based on this information. (Hint: You should use both the relationship between AG° and K, and the relationship between the Gibbs energy, enthalpy, and entropy in this problem. Setting up your analysis as a least-squares linear fit provides the best result.)
