High pressure causes a decrease of the mobility of excess electrons in both benzene and toluene.These decreases are interpreted as a shift in the equilibrium e-s + A <*> A- in favor of the anions (A-) at high pressure.These attachment reactions are favored at high pressure by large negative volume changes of between -100 and -180 cm3/mol, which are attributed to electrostriction of the solvent by the anion.Above 1.5 kbar the mobility becomes independent of pressure.Transport under these conditions involves electron hopping from the anion to a neighboring molecule.
