Interaction Potential Energy

Postby Christine Chen 1H » Mon Nov 12, 2018 5:57 pm

In the formula Ep is equivalent to (a1*a2)/r^6, what do the alpha and r values represent?

Alpha represents the polarizability, which depends on the number of electrons and the size of the atom or molecule.
r is the distance between the two atoms or molecules.

The potential energy equation shows that an increase in size or molar mass,, or a decrease in distance, leads to a stronger attraction between atoms or molecules.

Will we use the potential energy equation in test 3 and/or the final exam?

At the very least, its a good idea to know the general concept behind the Ep equation even if we are not using it for calculation questions. Also, general rule of thumb, whatever Dr. Lavelle goes over in class is fair game for the third test or the final exam.
