The potential energy function for the force between the two atoms in a diatomic molecule is approximately given by
\(U(x)=\frac{a}{x^{12}}-\frac{b}{x^{5}},\)
where, a and b are constants and x the distance between the atoms. If the dissociation energy of the molecule is defined as \(\square=\left[U(x=\infty)-U_{\text {at equiliarium }}\right] \text { ، }\) then D is
- \(\frac{b^{2}}{2 a}\)
- \(\frac{b^{2}}{12 a}\)
- \(\frac{b^{2}}{4 a}\)
- \(\frac{b^{2}}{6 a}\)
Answer
(C) b^ 2 4 a
