Consider the balanced chemical equation. H2O2(aq)+3I−(aq)+2H+(aq)→I3−(aq)+2H2O(l) In the first 14.0 s of the reaction, the concentration of I− drops from 1.000 M to 0.817 M Predict the rate of change in the concentration of H2O2 (Δ[H2O2]/Δt). Express the rate to three significant figures and include the appropriate units. (I understand the arithmetic, but I'm having a tough time with the units)
