what is equilibrium bond distanceSolutionBond length is the

Solution

Bond length is the experimentally determined average distance between two bonded atoms. Bonded atoms vibrate due to thermal energy available in the surroundings. The minimum energy occurs at the equilibrium distance r _0, which is where the bond length is measured. Thus r ₀ is called as the equilibrium bond distance for two atoms. The distance r is distance between two atoms at any energy level. That is why displacement x is written as -

x = r - r _0,
