Chemical Kinetics Factors Affecting Reaction Rate

Chemical kinetics deals with the experimental determination of reaction rates from which rate laws and rate constants are derived. Wood combustion for example has a high reaction rate because the process is fast whereas iron rusting has a low reaction rate since the process is sluggish.
