For the reaction below, the [I-] changes from 1.000 M to 0.565 M in the first 17 s. Calculate the rate of disappearance (in Ms-1) of H+ during this time.

H2O2 (aq) + 3 I-(aq) + 2 H+(aq) → I3-(aq) + 2 H2O(l)

Enter the positive answer to 3 decimal places. Do not include units. Make sure to round correctly.
