Someone please help me with Part A and Part B$!!!!$

The oxidation of iodide ion by arsenic acid, $H_{3}As{O}_4,$ is described by the balanced equation

$3I^{-}(aq)+H_{3}As{O}_4(aq)+2H^{+}(aq)$

$I_3^{-}(aq)+H_{3}As{O}_3(aq)+H_{2}O(l)$

Part A

If $-\frac{I^{-}}{}t=5\mathrm{.}1{10}^{-4}\frac{M}{s},$ what is the value of $\frac{I_3^{-}}{}t$ during the same time interval?

Express your answer using two significant figures.

$\frac{I_3^{-}}{}t=|$~$,\frac{M}{s}|$

Part B

What is the average rate of consumption of $H^{+}$during that time interval?

Express your answer using two significant figures.

$-\frac{H^{+}}{}t=[]\frac{M}{s}$
