More Book Details

Description of the Book:

Small crystals of lithium, potassium and cesium tungsten bronzes were prepared. Also nonstoichiometric gamma-tungsten trioxide was prepared. To study the catalytic activity of these bronzes a method of sintering them into gold was devised. The homogeneous oxidation of iodide by oxygen was studied. The rate constant at 25 degrees is 1/4 x 10 to the minus 5th power sec. The reaction is first order in oxygen and zero order in iodide and hydrogen ions. The activation energy is 16.9 kcal/mole. A very sensitive method of determining ion adsorption utilizing multiple reflection ellipsometry is suggested
