The oxidation of iodide ion by peroxy di...

The oxidation of iodide ion by peroxy disulphate ion is described by the equation :
`3I^(-)+ S_2O_8^(2-) to I_3^(-) + 2SO_4^(2-)`
If `-(Delta[S_2O_8^(2-)])/(Deltat)=1.5xx10^(-3) Ms^(-1)` for a particular time interval, what is the value of `-(Delta[I^-])/(Deltat)` for the same time interval ?
