For the net reaction 2 H2O2(aq)→2 H2O(l)+O2(g)\mathrm{2\,H_2O_2(aq) \rightarrow 2\,H_2O(l) + O_2(g)}, a mechanism is proposed: Step 1: H2O2(aq)+I−(aq)→H2O(l)+IO−(aq)\mathrm{H_2O_2(aq) + I^-(aq) \rightarrow H_2O(l) + IO^-(aq)} Step 2: H2O2(aq)+IO−(aq)→H2O(l)+O2(g)+I−(aq)\mathrm{H_2O_2(aq) + IO^-(aq) \rightarrow H_2O(l) + O_2(g) + I^-(aq)} Which statement correctly identifies a catalyst in the mechanism?
