One model for the potential energy of a twoatom molecule, where the atoms are separated by a distance 7', is 7 r 14 r 5 Uh") Uul(7\") , (7\") l Where To : 0.7 nm and U0 : 7.4 eV. Note: 1 eV = 1.6 x 10'19 J. Some helpful units: [Force] = eVm [Energy] : eV [distance]: nm Equilibrium Distance What is the distance between the atoms when the molecule is in stable equilibrium? Click here for a hint Force /\\ If the distance between the atoms increases from equilibrium by 7-1 : 0.45 nm, then what is the force from one atom on the other associated with this potential energy? (Enter your answer as postive if they repel each other, and negative if they attract.) Fr(7'eq + 7'1)
