Homework Statement
A hypothetical atom is diatomic containing two identical atoms separated by an equilibrium distance. About this distance the atoms vibrate with the electric forces providing an effective spring constant of k = 4.0×10^−3 N/m. As the temperature of the sample is increased the amplitude of the vibration increases. At what temperature will the rms displacement of the atoms be x= 5.0×10−10m? (Answer: 72 K)
Homework Equations
<E> = 7kT/2
U = 7nRT/2
The Attempt at a Solution
I assumed that because of spring like nature of the atoms, this atom was a diatomic non rigid rotator, which is how I have those relevant equations. I am unsure if this initial assumption is even correct. Even if it was, I still don't have an idea of how to proceed from there.
