Abstract
The accelerating role of water in the insertion of hydrogen into tungs ten trioxide WO3 was studied in non-aqueous aprotic and/or protic reac tion media and in aqueous solutions of the sulfuric acid. The activati on energies of hydrogen insertion in various reaction media were estim ated. The partial molar heat of hydrogen insertion DELTAH = 8.7+/-1.2 kJ/mole of H0.45WO3 was evaluated.
