The last part of General Chemistry course in the Faculties of Engineering and Agricultural Sciences at my University is

I believe the Nernst equation (below) to be one of the most elegant results of thermodynamics, as well as a really powerful tool for a society which heavily relies on electricity – and, thus, desperately needs it, both for big factories and for personal mobile phones!

However, I usually find that students believe this equation to be difficult to

Nernst equation contains every dream of scientists: work, equilibrium constants, logarithms, and

The major issue comes from what it’s inside the logarithm; to correctly use it, one should use

Another problem usually arises when considering the difference between

A difficulty (and usual question) is the following: if I have to use the same number of electrons when balancing the

The truth is: of course, the number of electron involved in each semireaction DOES count, but you already take it into account when calculating the equation… if you double the number of electrons, also exponents in the logarithm double, and so the global effect is null. For this reason, you can use both methods to calculate the emf in your cell (how nice!).

Lastly, the answer to the title question: Nernst equation is simple enough to be used, and so I deem the pronounciation more difficult. Right? Well, unless you have help 🙂
