Question

The oxidation of iodide ion by arsenic acid, H3AsO4, is described by the balanced equation
3I−(aq)+H3AsO4(aq)+2H+(aq)→ I3−(aq)+H3AsO3(aq)+H2O(l)

If −Δ[I−]/Δt = 4.8×10−4M/s , what is the value of Δ[I3−]/Δt during the same time interval?
Express your answer using two significant figures.

What is the average rate of consumption of H+ during that time interval?
