(a) Why the rate constant of a reaction decreases with increasing activation energy has to be explained. Concept introduction: Arrhenius equation: Arrhenius equation is a formula that represents the temperature dependence of reaction rates The Arrhenius equation has ...
Several rational models are constructed to show why the ratio of a country's foreign trade to its GNP should decrease with increasing country size. A physics-inspired model of absorption of a quasi-continuous particle flow by a quasi-homogeneous space results in detailed agreement with the ...

thermodynamics yields no information about the rate of the reaction. Because the tools and concepts of thermodynamics are very powerful, they were extended to allow an understanding of why reactions occur with different rates. If a maximum energy state exists intermediate between S and P, and...
