12 kcal. The number of hydrogen ions, n, which are involved may be as large as four. The rate of the reaction depends on the fourth power of the concentration of nitric acid. Equilibrium data were obtained. The over-all reaction is slightly endothermic. Equilibrium data are given. Depending on the composition of the aqueous phases the major fraction of the neptunium may be in the hexavalent state at
