... HCN conversion increased rapidly with an increase in reaction temperature between 165 and 277 °C. Because HCN oxidation is an exothermic process, raising the reaction temperature will decrease HCN conversion if it is a thermodynamically limited process. Our results show that HCN oxidation under thes ...

Catalysis
Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.
