NuevoAQA JUNE 2026 Chemistry AS LEVEL 7404 PAPER 2 Exam Guide - Complete Solutions Updated Iodide ions are oxidised to iodine by hydrogen peroxide in acidic conditions. H2O2(aq) + 2H+(aq) + 2I-(aq) → I2(aq) + 2H2O(l) The rate equation for this reaction can be written as rate = k [H2O2]a [I-]b [H+]c In an experiment to determine the order with respect to H+(aq), a reaction mixture is made containing H+(aq) with a concentration of 0.500 mol dm-3 A large excess of both H2O2 and I- is use...
