### How to apply a certain voltage vs SHE

For one of my projects, I must apply a voltage at the electrodes of -1V and +2V vs SHE. But my device potentiostat picks a voltages of 3V. How am i certain that it doesn't apply the voltage between -...

### Equilibrium chemical potential if the population is not conserved?

The chemical potential, $\mu$, is equal to the free energy $F$, per photon. $$F = \mu = u-Ts$$ The energy per photon is $u=h\nu$ and $s$ is the entropy per photon. Say we have a process where an ...

### Finding Potential Depth of Multiple-Minimum in a PEC

Suppose we have the following curve with more than one well and different maximum points: My simple question is how to calculate the potential depth of each well? Do we calculate all the potential ...

### Is equilibrium point for a coupled equilibria of arbitary number of coupled reactions is a unique point?

I was solving a question of salt hydrolysis for a mixture of Weak Acid-Base Salts, given the initial amount of salt and Equilibrium constants. I was trying to approach the problem in two ways, ...

### Do helium and neon form "stable" chemical compounds?

Helium and neon are the two most unreactive elements in the Periodic Table, but could they form compounds with an element such as fluorine that won't spontaneously explode and decompose outside of ...

### Enthalpy in the van't Hoff equation

In the van't Hoff equation, why do we say that the change in enthalpy at standard pressure is constant? My book derives the equation for a mixture of ideal gases reacting with each other. The proof ...

### Do high-energy chemical bonds indicate strong chemical bonds?

In my head it seems reasonable that a high-energy bond would indicate that the bond is strong, however a question got me thinking. Take for example lead azide, a very explosive compound that is often ...
