WebWhen an oxygen molecule O* 2 * lands on the platinum catalyst, it can stick to it with the oxygen-oxygen bond slightly weakened. In other words, the metal helps partially cleave the oxygen-oxygen bond. Once you add a little bit of heat, the oxygen molecule will fall part into two oxygen atoms. These atoms can then go on to oxidize CO to CO* 2 ... WebGCSE Chemistry – Catalysts. In a catalysed reaction, the activation energy is at a lower level.
