Question
The potential energy function for the force between two atoms in a diatomic molecule is approximately given by U(x) = 
where a and b are constants and x is the distance between the atoms. If the dissociation energy of the molecule is D = [U(x = ∞) - Uat equilibrium], D is
where a and b are constants and x is the distance between the atoms. If the dissociation energy of the molecule is D = [U(x = ∞) - Uat equilibrium], D isOptions
A.
B.
C.
D.
Solution
U(x) = 
U(x = ∞) = 0
as,
at equilibrium, F = 0
∴
∴ Uat equilibrium =
∴ D = [U(x = ∞) - Uat equilibrium] =
U(x = ∞) = 0
as,
at equilibrium, F = 0
∴
∴ Uat equilibrium =
∴ D = [U(x = ∞) - Uat equilibrium] =
