The Profound Unravelling of Equilibrium Thermodynamics and Arrhenius First-Order Kinetics in Relation to Metal Hydride Desorption Reactions

Roland Hermann Pawelke FOTEC Forschungs- und Technologietransfer GmbH


Approaching the entanglement problem of kinetics with thermodynamics in reversible metal hydride desorption reactions by means of a hyperbola template such as the Michaelis-Menten curve renders a closed solution for their unravelling possible, revealing profound insight of general significance into both, the structure of the rate-limiting thermodynamic factor and the nature of experiment-specific first-order Arrhenius kinetics. As by-product an alternate method of extreme simplicity for modelling transient behaviour of reversible metal hydride tanks is obtained. This paper concludes a series of works concerned with objectively approaching metal hydride soprtion reaction kinetics.

Version notes

V2: The paper has been given a revision and a different emphasis: it is less about actual tank modelling but the complete objective untangling of first-order kinetics and equilibrium thermodynamics ensuing from this approach, which is quite awesome. The title has changed accordingly.
