The homogeneous gas-phase decomposition kinetics of silane has been investigated using the single-pulse shock tube comparative rate technique (T = 1035-1184ยฐK, P ~d = 4000 Torr). The initial reaction of the decomposition SiH4 ! + SiHz + H2 is a unimolecular process in its pressure fall-off regime w

The homogeneous gas-phase thermal decomposition kinetics of germane have been measured in a single-pulse shock tube between 950 and 1060 K at pressures around 4000 torr. The initial decomposition is GeH4 -GeH2 + H2 in its pressure-dependent regime, with log k ~~~~( 4 m ) = 13.83 f 0.78 -50,750 f 357
At 298 K the rate constant for the decomposition of N-chloroleucine has the constant value 3.20 >: lo-\* s-' over the range pH 5-12, increases with increasing acidity at pH < 5, and increases with pH a t pH > 12. A mechanism is put forward which explains these results.
