Question 7
A reaction solution is prepared with [S2O32] = 0.0500 M and [I-] = 0.0400 M. The
reaction is timed to the point where the reaction has consumed 1.00% of the
peroxydisulphate. It takes the reaction 150 seconds to reach this point. What is the
average initial rate of this reaction?
3.33 х 10-6 М.s-1
3.30 x 10-4 M-s-1
O 2.00 x 10-3 M.s-1
6.67 x 10-6 M.s-1
Question
A reaction has been found to proceed acording to the following rate law:
Rate = k [A] [B]2
The initial rate is found to be 0.0400 M-s1 when the inital concentrations are [A] =
0.0500 M and [B] = 0.0300 M. What is the reaction rate constant?
O 26.7 M-1.s-1
O 0.00113 M-2.s-1
6.00 x 10-5 M-1.s-1
889 M-2.s-1
1.80 x 10-6 M-2.5-1
533 M-2.s-1
