The energy of a covalent bond as a function of interatomic distance, r, is described by the following equation: in this equation, energy is expressed in units of kj•mol−1 and distance in å. what is the equation that describes the force with respect to position? what is the energy when the interatomic distance is 2 å? at the same value of the interatomic distance, what is the force and is the force pushing the bonded atoms closer together or further apart?
