G A. Poskrebyshev, Pedatsur Neta, Robert E. Huie
… 298 K, pKa298( OH) = 11.57 0.04 and DionGo298( OH) = (66.4 0.2) kJ mol-1. From the temperature dependence of Ka( OH) we calculate DionHo298( OH) = (24.4 0.5) kJ mol-1 and DionSo298( OH) = (-141 2) J mol-1 K-1. … DfHo298(O -) = (17.3 to 20.2) kJ mol-1 and So298(O -) = -45 J mol-1 K-1 for O -. The activation energy for the …
