Abstract
In   this study  two  amino acids were chosen (DL.alanine,DL.serine) to determine  their effect  on dissociation of S2O8-2  ino. As  the reaction was very slow, Ag+ ino was used as a catalyst. The kinetics  measurement  showed  that  the reactions  in  both   cases  were  found  in the first order with  respect to  S2O8-2 , half  order with  respect   to  Ag+ and zero  order  with respect  to substrates . Mechanisms  were proposed   for  these  reactions  according  to  the  determined orders. The energy  of  activation  (AE) was  determined  for each  reaction, and  was found  to  by  30.50 k   JmoI-1  in case  of  DL. Serine   and   24.40 k JmoI-1  in case  of   DL. alanine.
