From the point of view of the scale hierarchy (Salthe, 1985; 1993, Chapter 2; 2002 c), (4) we could quite reasonably take the stages in deploying the coal to be actual steps in its dissipation, thereby considering a lump of coal in the hopper (or, for that matter, in the rubble at the base of the mountain) to be closer to thermodynamic equilibrium than when it was part of a mountain.
The application of the Gibbs-Duhem equation (Guggenheim 1967) on Eqn 4 allows the derivation of equations that enable the calculations of the thermodynamic equilibrium constant and the activity coefficients of adsorbed ions.
If Planck was so forceful in his comment, he rested his case on solid grounds: "It is only in the case of stable thermodynamic equilibrium that there is but one temperature, which then is common to the medium itself and to all rays whatever color crossing it in different directions" [22, [section]101].
