The reaction 2 ClO2(aq) + 2 OH-(aq) ClO3-(aq) + ClO3-(aq) + H2O(l) was studied at a certain temperature with the following results:
Experiment [ClO2(aq)] (M) [OH-(aq)] (M) Rate (M/s)
1 0.0468 0.0468 0.0318
2 0.0468 0.0936 0.0636
3 0.0936 0.0468 0.127
4 0.0936 0.0936 0.254
(a) What is the rate law for this reaction?
Rate = k [ClO2(aq)] [OH-(aq)]
Rate = k [ClO2(aq)]2 [OH-(aq)]
Rate = k [ClO2(aq)] [OH-(aq)]2
Rate = k [ClO2(aq)]2 [OH-(aq)]2
Rate = k [ClO2(aq)] [OH-(aq)]3
Rate = k [ClO2(aq)]4 [OH-(aq)]
(b) What is the value of the rate constant?
(c) What is the reaction rate when the concentration of ClO2(aq) is 0.0613 M and that of OH-(aq) is 0.130 M if the temperature is the same as that used to obtain the data shown above?
