✦ Synopsis

The kinetics of bimolecular diffusion-controlled chemical reactions in a presence of shear flow is considered. It is shown that if the second-order rate constant is time-independent in an immobile medium, the influence of flow on the reaction rate is negligible. However, when the rate constant is a decreasing function of time, the flow will result in establishing a time-independent rate constant after a time 1 /(u ((u is the velocity gradient), and the reaction rate at times t x=-1 /a! can be much higher than in an immobile medium.
