[Audio] Chemical KineticsChemical kinetics is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It provides evidence for the mechanism of chemical reactions . To study the RATE of chemical reactions. A+B=C One can monitor the appearance of products, or the disappearance of reactants. R = d[C]/dt R = -d[A]/ dt The rate of this elementary (single-step) reaction may be expressed: R=k[A][ B] So, for example, doubling the concentration of reactant A doubles the reaction rate . Similarly, cutting the concentration of reactant B by a factor of five reduces the rate by that same amount . k is the rate constant..
