Equilibrium in the Exchange of Hydrogen between Arsine and Water

Equilibrium in the Exchange of Hydrogen between Arsine and Water

The equilibrium constant for the reaction AsH2D(g)+H2O(l)⇌AsH3(g)+HDO(l) has been measured at 25.4° and found to be 1.89±0.02, corresponding to a value in the gas phase of 1.77±0.02. With the known vibrational spectra of AsH3 and AsH3—d3 the gas phase equilibrium constant was calculated at 25.4°, K2...

Zusammenfassung:The equilibrium constant for the reaction AsH2D(g)+H2O(l)⇌AsH3(g)+HDO(l) has been measured at 25.4° and found to be 1.89±0.02, corresponding to a value in the gas phase of 1.77±0.02. With the known vibrational spectra of AsH3 and AsH3—d3 the gas phase equilibrium constant was calculated at 25.4°, K2=0.777e258/T=1.84.
