A zero-order reaction is characterized by a constant reaction rate, independent of the concentrations of the reactants. Unlike many chemical reactions, increasing or decreasing the amount of reactant does not influence the reaction speed. The rate law for a zero-order reaction is simply Rate = k, where \u2018k\u2019 represents the zero-order rate constant. This behaviour frequently occurs when a catalyst or enzyme is fully saturated, meaning all of its active sites are occupied. Consequently, the concentration of reactants decreases linearly with time. Understanding zero-order kinetics is vital in fields such as catalysis and pharmacology, where it\u2019s crucial to predict reaction behaviour under specific conditions involving saturated catalysts or enzymes.<\/p>\n","protected":false},"excerpt":{"rendered":"
