Chemical kinetics rate laws

WebSep 12, 2024 · For zero-order reactions, the differential rate law is: Rate = k[A]0 = k A zero-order reaction thus exhibits a constant reaction rate, regardless of the concentration of its reactants. The integrated rate law for a zero-order reaction also has the form of the equation of a straight line: [A] = − kt + [A]0 y = mx + b http://guweb2.gonzaga.edu/faculty/cronk/CHEM101pub/chemical_kinetics.html
