http://www.eng.utah.edu/~lzang/images/lecture-1.pdf WebIn brief summary: Thermodynamics tells us that a reaction should go if the products are more stable (have a lower free energy) than the reactants --- the reaction has a negative free energy change. Kinetics, on the other hand, tells us how fast the reaction will go, though doesn't tell us anything about the final state of things once it gets there.
Web17 nov. 2024 · The description of the reaction kinetics follows a previously published non-linear physical model of a direct methanol fuel cell by Krewer et al. 28 which is based on the MOR mechanism shown above.

This is also known as kinetic perfection or catalytic perfection.Since the rate of catalysis of such enzymes is set by the diffusion-controlled reaction, it therefore represents an …
