The following initial rate data apply to the reaction F₂(g) + 2Cl₂O(g) → 2FClO₂(g) + Cl₂(g). Which of the following is the rate law for this reaction? A) rate = k[F₂]²[Cl₂O]⁴ B) rate = k[F₂]²[Cl₂O] C) rate = k[F₂][Cl₂O] D) rate = k[F₂][Cl₂O]² E) rate = k[F₂]²[Cl₂O]²

The rate law for this reaction can be determined by analyzing the initial rate data. Since the reaction is second order overall (sum of the exponents in the rate law is 2), the rate law must be of the form rate = k[A][B], where A and B are the reactants. Option C is the only one that matches this form, so it is the best choice. The other options either include a term that is raised to a power greater than 1 or include an additional reactant that is not part of the reaction.
