### Why does the equation for chemical potential apply to liquids and aqueous solutes?

What is A ? Is it the generic name of any chemical ? Is it the absorbance of a colored stuff ? Why don't you call $p$ as $p$(A) or ${p_A}$ ? What is $\pu{\chi}_A$ ? Is it the molar fraction ? Anyway ...

### Is Gibbs free energy change applicable to forward and reverse reactions at equilibrium?

Being a professor, the most difficult thing to instill in the mind of students is that thermodynamics don't consider microscopic changes. Koushal, you did the same thing. In calculating the change in ...

### Is Gibbs free energy change applicable to forward and reverse reactions at equilibrium?

First you considered the reaction reversible: $$\ce{A + B <=> C + D}\tag{R1}$$ Then you considered each reaction irreversible to determine its $\Delta_\mathrm{r}G:$ \begin{align} \ce{A + B &-...

### Mathematical models of Vaporization-Condensation dynamics

What you're trying to develop is a kinetic model of a gas-liquid equilibrium. There are are such models, but I'm afraid yours won't work. The reason your model won't work is that it says the rate of ...

### Mathematical models of Vaporization-Condensation dynamics

I fail to see how this explains anything about the equilibrium between liquid and vapor. At equilibrium the free energy change between gas and liquid is zero and is independent of the amount of ...

### Why is this equation true for a salt in acid?

It is an example for parallel reaction. The reactions taking place are $\ce{SrF2 <=> Sr^2+ +2F−}$ and $\ce{H+ +F− <=> HF}$. The $\ce{F−}$ ions formed from the first reaction reacts ...

### Electrode potential for saturated silver carbonate solution

Where is the problem? Let's call $s$ the solubility of $\ce{Ag2CO3}$. As a consequence $[\ce{Ag+}] = 2s,$ and $[\ce{CO3^2-}] = s.$ So the solubility product is K_\mathrm{s} = [\ce{Ag+}]^2\,[\ce{CO3^...

It's sometimes not obvious because of the way the subject may be taught, but $\Delta_rG$ is what's called a differential form, so it actually describes how the free energy changes as the reaction ...
