Consider the following balanced chemical equation:

H₂O_{2 (aq)} + 3 I^-_(aq) + 2 H⁺_(aq) I₃^- _(aq) + 2 H₂O _(l)

In the first 58.4 seconds of the reaction, the concentration of I₃^- increased from 0.613 M to 1.136 M.

What is the average reaction rate over this time interval (in mol L^-1 s^-1)?

Remember: if you want to express an answer in scientific notation, use the letter "E". For example "4.32 x 10⁴" should be entered as "4.32E4".
