Second-order reactions

Second-order reactions are chemical processes where the rate depends on the concentration of two reactants or the square of a single reactant's concentration. This means that as the amount of reactant(s) increases, the reaction speeds up significantly. For example, if you double one reactant or both reactants together, the reaction rate can increase four times for a single reactant case. These reactions often involve the collision of two molecules, and their rates can be described mathematically by specific equations that relate the reaction speed to reactant concentrations.
