. Like any equilibrium constant, Kw, changes with temperature. (a) Given that autoionization is endothermic, how does Kw change with rising T? Explain with a reaction that includes heat as a reactant or product. (b) In many medical applications, the value of Kw at 37°C (body T) may be more appropriate than the value at 25°C, 1.0x10-14. The pH of pure at 37°C is 6.80. Calculate Kw, pOH and [OH-] at this T.
