Solvent effect on reaction rate pdf
Web1.4. Solvent Effect on Reaction Rate The solvent effect on reaction rate are best treated in terms of the thermodynamics of hypothetical equilibrium between reactant and transition state, i.e., in the frame of the absolute rate theory rather than collision theory [7, 8]. The specific rate of a chemical reaction depends on the WebChemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate.Chemical kinetics includes investigations of how …
