Kinetics Calculator

Chemical kinetics is the study of reaction rates and the factors that affect them. It helps us understand how fast reactions occur and what influences their speed, from temperature and concentration to catalysts and reaction mechanisms.

Different reaction orders follow different rate laws. Zero-order reactions have constant rates, first-order reactions depend on one reactant's concentration, and second-order reactions depend on the product of concentrations or the square of a single concentration.

Select the reaction order, choose what to calculate (concentration, time, or half-life), and enter the known values. The calculator will apply the appropriate integrated rate law and show the calculation steps.

Half-life is the time required for the concentration of a reactant to decrease to half its initial value. It varies with reaction order: constant for first-order reactions, concentration-dependent for second-order reactions, and initial concentration-dependent for zero-order reactions.
