Fenske equation

The Fenske equation is a way of measuring the energy efficiency of different types of molecules. It's useful for deciding which molecules to use in chemical processes and experiments. The equation looks like this:
Efficiency = (1/(R + 1)) · (1/v)
Where "R" is the number of atoms in the molecule, and "v" is the number of atoms that are bonded together.

The Fenske equation tells us that molecules that have fewer atoms and more bonding between them will be more efficient. That means that a molecule with 5 atoms and 3 bonds will be more efficient than a molecule with 10 atoms and 5 bonds. The equation helps us choose molecules that will be more efficient and give us better results.
