Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; … See more Example An illustrative example is the effect of catalysts to speed the decomposition of hydrogen peroxide into water and oxygen: 2 H2O2 → 2 H2O + O2 This reaction … See more Estimates are that 90% of all commercially produced chemical products involve catalysts at some stage in the process of their manufacture. In 2005, catalytic processes generated about $900 billion in products worldwide. The global demand for catalysts in 2014 … See more An added substance that lowers the rate is called a reaction inhibitor if reversible and catalyst poisons if irreversible.
