← A graph of potential energy for an endothermic reaction puts the reactants at 0, the activated complex at +118 kJ/mol and the products at +27 kJ/mol. The reverse reaction needs a minimum energy of how much?Iron(II) ions catalyse the oxidation of iodide ions by peroxodisulphate ions. The steps are: S₂O₈²⁻ + 2Fe²⁺ → 2SO₄²⁻ + 2Fe³⁺, then 2Fe³⁺ + 2I⁻ → 2Fe²⁺ + I₂. Which line names the catalyst and the intermediate? →
