Question

The following initial rate data apply to the reaction F2(g) + 2Cl2O(g) ® 2ClO2(g) + Cl2(g).Which of the following is the rate law (rate equation) for this reaction?rate = k[F2][Cl2O]rate = k[F2]2[Cl2O]2rate = k[F2][Cl2O]2rate = k[F2]2[Cl2O]4rate = k[F2]2[Cl2O]

Answer 1

Answer: k [
`F_(2)`]
`[Cl_(2)O]^(2)`

Explanation: The given reaction is -

`F_(2)(g) + 2Cl_(2)O(g) \rightarrow  2ClO_(2)(g) + Cl_(2)`

The rate law of the reaction is the written as the concentration of the reactant species rest to the power of its stiochiomeric coefficient.

Thus the rate law of the given reaction can be written as -

Rate = k [
`F_(2)`]
`[Cl_(2)O]^(2)`

Rate law usually is determined from the slowest step of the reaction.
