Influence of monovalent cations on the rates of dibromosuccinate and hydroxide ions.
The rate constants for the reaction between dibromosuccinate and hydroxide ions have been determined in the presence of lithium and sodium chloride. Effects of temperatures and added electrolytes on this reaction have also been examined. It has been found that smaller radii have less accelerating effects on the rate of reaction. The activation parameters such as apparent energy of activation (Ea), change in enthalpy of activation (DeltaH#), change in entropy of activation (DeltaS#) and change in free energy of activation (DeltaG#) have been calculated in the absence and presence of lithium and sodium chloride for the reaction and discussed.
