Query: Revisiting Trends in the Exchange Current for Hydrogen Evolution   N{\o}rskov and collaborators proposed a simple kinetic model to explain the
volcano relation for the hydrogen evolution reaction on transition metal
surfaces in such that $ j_0= k_0 f({\Delta}G_H)$ where j_0 is the exchange
current density, $f({\Delta}G_H)$ is a function of the hydrogen adsorption free
energy ${\Delta}G_H$ as computed from density functional theory, and $k_0$ is a
universal rate constant. Herein, focusing on the hydrogen evolution reaction in
acidic medium, we revisit the original experimental data and find that the
fidelity of this kinetic model can be significantly improved by invoking
metal-dependence on $k_0$ such that the logarithm of $k_0$ linearly depends on
the absolute value of ${\Delta}G_H$. We further confirm this relationship using
additional experimental data points obtained from a critical review of the
available literature. Our analyses show that the new model decreases the
discrepancy between calculated and experimental exchange current density values
by up to four orders of magnitude. Furthermore, we show the model can be
further improved using machine learning and statistical inference methods that
integrate additional material properties
