The analytical kinetics of the titanium(III)-perchlorate reaction-I Homogeneous reaction kinetics
Abstract:
A spectrophotometric investigation has been made of the analytically relevant kinetics of the titanium(III)-perchlorate reaction in chloride and sulphate media. Sulphate media give better and more reproducible results. The reaction in sulphate medium is first-order in titanium(III) and hydrogen ion, but of fractional order in perchlorate. The pseudo third-order rate constant k(3)' for the rate equation has a value of 4.22 +/- 0.15 l(2) mol(-2) s(-1) at 49 degrees C. The energy of activation in sulphate medium is 84 +/- 4 kJ mol(-1), and in chloride medium is 80 +/- 12 kJ mol(-1). Small amounts of chloride m a sulphate medium, or of sulphate in a chloride medium, retard the reaction. The basis has been laid for a rate-measurement method for determination of perchlorate at low concentrations.

SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a reaction.
