How Does Reactant Concentration Affect Reaction Rate?
According to the rate law, the rate of a reaction is proportional to the concentration of the reactants raised to a power, often determined experimentally. In catalysis, the presence of a catalyst can modify this rate constant. For instance, in enzyme catalysis, the reaction rate can depend on the Michaelis-Menten kinetics, where the rate initially increases with substrate concentration but eventually levels off when the enzyme becomes saturated.
