Question

The data in the table below were obtained for the reaction: 2 ClO 2 (aq) + 2 OH - (aq) →ClO 3 - (aq) + ClO 2 - (aq) + H 2 O (1) -What is the order of the reaction with respect to ClO₂?

Quizplus · Accepted Answer

The reaction rate can be written as: Rate = k[ClO₂]^x[OH^-]^y where k is the rate constant and x and y are the orders of the reaction with respect to ClO₂ and OH^- respectively. From the given data, the initial rate doubles when the concentration of ClO₂ is doubled, indicating that the reaction rate is directly proportional to the square of the concentration of ClO₂. Therefore, x = 2. Hence, the order of the reaction with respect to ClO₂ is 2 or option B.
