How does cell potential change with temperature for positive enthalpy and negative entropy?

The equation $\Delta G_r=-nFE$ helps as does $\displaystyle \Delta S_r=\left(\frac{\partial E}{\partial T}\right)_pnF$ where $\Delta G_r$ is the reaction free energy. The slope $\displaystyle \frac{\...

Fundamental understanding of electrode potentials

Consider an electrode immersed into an electrolyte, two things can occur. Metal ion $M^{n+}$ from the solution may collide with the electrode, gaining $n$ electrons from it, and convert to metal ...

Fundamental understanding of electrode potentials

Negative charge is kept near surface by attraction of excess positive ions in solution. The reason for ions going into solution and electrons staying in metal is electron's De broglie wavelength ...

Silver Tarnish and Reactivity Series

We do indeed have an exothermic reaction between hydrogen sulfide and silver, which goes against the usual EMF series. The EMF series applies specifically to species in water solution, so we should ...

Silver Tarnish and Reactivity Series

Though this is looked at as a displacement reaction, this reaction here is more of an redox reaction. Let me elaborate.. (Ag) is less reactive than (H) in reactivity series meaning (Ag) can't displace ...
