✦ Synopsis

In practical applications such as combustion studies, prediction of the pressure dependence of unimolecular reaction steps is made more difficult by the great variety of conditions (pressure, temperature and composition) arising in the medium. A general scheme for the treatment of pressure dependence is needed. Here we investigate the pressure dependence of the collision efficiencies of weak colliders in a multicomponent medidm. An extrapolation method is presented which can account for such pressure dependence by reference to single-component data. The scheme is tested on a model for the decomposition ofethane in a mixture of a strong and a weak collider.
