Abstract
Linear response theory is used to obtain an expression for the chemical relaxation rate in terms of the time integral of a correlation function. The important quantity is the time derivative of the progress variable. This expression is evaluated in the finite‐temperature Green function representation. The familiar cross‐section expression for the rate constants is obtained. A similar theory for vibrational relaxation in dilute gases is presented.Keywords
