Equation 1 · Part 2 · Chemical Dynamics and Catalysis in 2035: Scenarios, Signals, and Falsifiable Predictions

Symbol E_a

r \propto \exp\!\left(-\frac{E_a(\Delta E_{\text{bind}})}{k_B T}\right)

E_a

What this part means

itself a function of the binding energy $\Delta$ $E_{\text{bind}}$ , so tuning a catalyst is really tuning where on that curve a given surface sits — through composition, structure, and the local electronic environment around active sites.

Its job in the formula

$E_a$ occurs above the fraction bar. The numerator is divided by the entire denominator below it.

Where the article explains it

Here the activation energy $E_a$ is itself a function of the binding energy $\Delta$ $E_{\text{bind}}$ , so tuning a catalyst is really tuning where on that curve a given surface sits — through composition, structure, and the local electronic environment around active sites.

The passage around this formula

…leaves. Plotted against binding energy, catalytic activity for a given reaction traces an inverted-U — the Sabatier principle — and the best catalysts sit as close as possible to the peak. Here the activation energy $E_a$ is itself a function of the binding energy $\Delta$ $E_{\text{bind}}$ , so tuning a catalyst is really tuning where on that curve a given surface sits — through composition, structure, and the local electronic environment around active sites. This is why catalyst discovery is not a search over…
