 Abstract    flu e n c e o f S tr u c tu r e B r e a k in g a n d S tr u c tu r e F o rm in g Io n s o n th e D is s o c ia tio n M e c h a n is m o f A c e tic A c id in A q u e o u s S o lu tio n s Dedicated to Professor W. V ielstich on the Ocassion of his 65th Birthday. Using a rotating disc electrode, the dissociation rate of acetic acid in various aqueous electrolyte solutions is studied. Li + , Cs+ and (CH3)4N+ at 1 M concentration considerably modify the activa­ tion enthalpy and entropy of the reaction. Evidently the interaction between the cations and water influences the dissociation mechanism of the weak acid. In the presence of 1 molar Li+ the activated complex of acetic acid seems to contain only one water molecule instead of two in the other cases.
