Question

determine rate law

The data below were determined for the reaction shown below.

S2O8 2– + 3I – (aq)—> 2SO42– + I3 –

Expt. # [S2O82–][I –]Initial Rate
10.0380.0601.4 x 10 – 5 M/s
20.0760.0602.8 x 10 – 5 M/s
30.0760.0301.4 x 10 – 5 M/s
The rate law for this reaction must be:

Question 2 options:

rate = k[S2O82– ][I –]3

rate = k[S2O82–]

rate = k[S2O82–]2[I –]2

rate = k[I –]

rate = k[S2O82–][I –]
