It should always be home in mind that solvent effects can modify the energy of both tile reactants and the transition slate. It is the difference in the two solvation effects that is the basis for changes in activation energies and reaction rates. Ihus, although it is conimon to express solvent effects solely in terms of reactant solvation or transition-slate solvation,... [Pg.242]

The original ideas of Evans and Polanyi [1] to explain such a Hnear relation between activation energy and reaction energy can be illustrated through a two-dimensional analysis of two crossing potential energy curves. [Pg.5]

This calculation shows that reaction energies and reaction enthalpies are usually about the same, even when reactions Involve gases. For this reason, chemists often use A 5 reaction nd A reaction interchangeably. Because many everyday processes occur at constant pressure, thermodynamic tables usually give values for enthalpy changes. Nevertheless, bear In mind that these are different thermodynamic quantities. For processes with modest AE values and significant volume changes, A " and A H can differ substantially. [Pg.403]

Trans. Faraday Soc. 34, 1 (1938). Herein is a transcript of a general discussion on the theoretical methods of treating activation energy and reaction velocity among whose contributors are H. Eyring, M. G. Evans, M. Polanyi, E. Wigner, N. B. Slater, and C. N. Hinshelwood. [Pg.233]

Since the investigations often focused on trends and their rationalization, we refrained from correcting stabilization energies and reaction barriers for... [Pg.294]

The link between the microscopic description of the reaction dynamics and the macroscopic kinetics that can be measured in a catalytic reactor is a micro-kinetic model. Such a model will start from binding energies and reaction rate constants deduced from surface science experiments on well defined single crystal surfaces and relate this to the macroscopic kinetics of the reaction. [Pg.81]

It is imperative that anyone attempting to understand the kinetics of the gas-carbon reactions also understand the role which the above steps (separately or in combination) can play in affecting values determined for orders of reaction, activation energies, and reaction rates. In the field of... [Pg.164]
