When does a chemical bond form between two atoms? Select one : O a. When attractive forces are greater than repulsive forces.
O b. When potential energy is lowest for the pair.
O c. When potential energy is greatest for the pair .
O d. When repulsive forces are greater than attractive forces.

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
