The formation of iodine is described by the following chemical equation: Suppose a two-step mechanism is proposed for this reaction, beginning with this elementary reaction: Suppose also that the second step of the mechanism should be bimolecular. Suggest a reasonable second step. That is, write the balanced chemical equation of a bimolecular elementary reaction that would complete the proposed mechanism.

ANSWER: Answer retrieved from ALEKS: HI(g) + ICI(g) ===> I_2(g) + HCl(g)
