“…A kinetic study is a first important step in this direction. These factors prompted the authors to carry out the solid state thermal and photochemical decomposition of transition metal peroxo compounds on an elemental basis (7)(8)(9)(10)(11)(12) to determine the generalities, trends, or differences in the mode of decomposition by changing the cation, anion, or the nature of peroxide linkages etc. This paper is a part of this series and reports the isothermal and photochemical decomposition of K,TaO,F,.H,O.…”
