equilibrium constant is inversely proportional to the process pressure. The model, however, overvalued the quantity of hydrogen and underestimated the production of methane. This was attributed to the typical behaviour of the equilibrium model. It was commented that this behaviour could be explained by...
That restriction does not apply to a non-equilibrium state, which has a large number of degrees of freedom. Heat can be removed from a non-equilibrium system, while both energy and volume are kept constant, by immersing the system in a heat bath. Then the system has to reach equilibrium ...
Knowledge of the thermodynamic potential in terms of the independent variables allows to characterize the macroscopic state of the system. However, in practice, it is difficult to access this potential experimentally due to irreversible transitions that occur between equilibrium states. A showcase example...
If the definition of t+273.15 = T (+273.15=T0, and 0 C) the relationship can be used to form more simple formula to express: V/T=V0/T0, V1/T1=V0/T0, V2/T2=V0/T0, furthermore, the natural V1/T1=V2/T2, namely gas at any temperature in a certain amount of pressure, ...
Hereafter, we explore the relationship between the uncertainty of each calorimetric data input and the impact on the predicted solubility (equilibrium) constant by conducting a sensitivity analysis for the example of analcime. First, we focus on the effect of the Gibbs free energy (ΔfG°, kJ·...

For each of the new potentials we consider the work available when the respective intensive canonical variable or variables are held constant. We then state the extremum principle, the equilibrium and stability conditions, and the Gibbs and the Euler equations for each potential. Brief reference ...
