Derive and expression for the stiffness of the bond at the equilibrium spacing, in terms of A , B , m , n , and r0 .
S=dFdr at r=r0 :
The energy-separation curve for two atoms, a distance, r, apart is: U(r)=−Arm+Brn
1) Derive an expression for the equilibrium spacing, r0, as a function of A, B, m, and n. Explicitly indicate multiplication with a * symbol.
r0 = ??
