Question

which area represents where a molecule is in a state of equilibrium between attractive and repulsive forces? 1 2 3

Explanation:

When a molecule is in a state of equilibrium between attractive and repulsive forces, the potential energy is at a minimum. This is because at this point, the net force acting on the atoms (due to inter - atomic forces) is zero. Looking at the potential energy vs internuclear distance graph, the minimum of the potential energy curve represents this equilibrium state.
