Abstract

The effects of molecular crowding on small molecule diffusion and chemical reactionrate coefficients are investigated. The systems considered comprise a randomdistribution of stationary spherical obstacles occupying a volume fractionϕ ofthe system and a large number of small molecules whose dynamics are followed. Chemical reactionsare studied in such crowded systems where, in addition to the obstacles, a large reactive sphereC is present that catalyses the reaction . Using a mesoscopic description of the dynamics employing multiparticle collisions among the small molecules,the ϕ dependence of the diffusion and reaction rate coefficients is computed. Boththe diffusion and reaction rate coefficients decrease with increase of theobstacle volume fraction as expected but variations of these quantities withϕ are not predicted by simple models of the dynamics.
