### Do "pseudo Van der Waals" gases exist?

In college, when deriving the Langmuir isotherm for gas-solid adsorption, the professor proposed a modified version of the Van der Waals state equation, what he called the "pseudo Van der Waals ...

### Total Differential of Chemical Potential

I have seen many sources (for example this libretext) cite that the total differential of chemical potential is $$d\mu = V_m dP - S_m dT$$ where $V_m$ is the molar volume and $S_m$ is the molar ...

### Question about chemical potential of a multicomponent ideal gas

Consider a pure ideal gas, i.e. only having one component. The chemical potential and free energy of this gas are as follows: $$\mu_1=\mu^\circ(T)+RT\ln\left(P\right)$$ $$G_1=n\mu_1$$ Where n is the ...

### Chemical potential and gibbs free energy

I would like to ask why the $\Delta_rG_1 = -RT\ln K + RT\ln Q$ is not equal to $Δ_rG_2$ numerically as shown in the figure where I derived $\Delta_rG_2 = RT\ln Q$ using a cyclic ring since $\Delta_rG$ ...
