What is the pre-exponential factor?

The pre-exponential, or frequency, factor is related to the amount of times molecules will hit in the orientation necessary to cause a reaction. It is important to note that the Arrhenius equation is based on the collision theory. It states that particles must collide with proper orientation and with enough energy.

Why is the pre-exponential factor related to collision theory and transition state theory?

Because the pre-exponential factor depends on frequency of collisions, it is related to collision theory and transition state theory. The Arrhenius equation introduces the relationships between rate and A, E a, and T, where A is the pre-exponential factor, E a is the activation energy, and T is the temperature.

What are the energetics of bond hydrolysis?

The energetics of bond hydrolysis ( EB) have been investigated for a wide range of minerals and structures, including oxides e.g 5 ., halides e.g 6 ., carbonates e.g 7 ., silicates and in particular, tectosilicates 8, 9, 10, 11, and orthosilicates 12, 13. A synthetic overview of EB values is provided in Table 1.

What is the G of CTEs hydrolysis in methanol and ethyl acetate?

The ?G ? of CTES hydrolysis in methanol and ethyl acetate resulted from an intermediate step which is re-esterification in the case of methanol, and hydrolysis of ethyl acetate at high temperature to produce acetic acid and ethanol, and autocatalysis by acetic acid.
