The kinetics of Mn(VII) oxidation of lysine in moderately sulfuric acid solutions was studiedspectrophotometrically in the presence and absence of Mn(II) as catalyst. The reaction was arrangedto be under pseudo first-order condition with respect to Mn(VII). The results showed that the pseudofirst-order rate constant increases with increasing [H2SO4], [(Mn)II], and [lysine]. The dependence ofthe...

In this research, a semi empirical approach has been suggested for calculating the activation energyof unimolecular thermal decomposition of vinyl ethers yielding saturated products. The calculationprocedure is based on the use of molecular mechanics (MM) methods. These methods which involvethe construction of the transition state for a molecule mainly consider the formation of a “HydrogenBridg...
