Abstract :
The rates for the reaction CO2+e-&rlhar2;CO 2- were determined in liquid 2.2-dimethylbutane (DMB) and isopentane (i-P) as a function of temperature. In 2,2-DMB both forward and reverse rates were measured over the 14-45°C range, while in i-P only the forward reaction was observed over 0-73°C. The rates and equilibrium constants are compared with those determined in other solvents, and the factors which influence these quantities in solutions are discussed. CO2 was found to be highly reactive in 2,2-DMB and i-P solutions. The reactivity in solution is understood in terms of energetics. Equilibrium for the reaction in solution is explained in terms of the total energy, given by the difference between the ground state energy of electrons in the solvent and the polarization energy due to the anion formed by electron attachment
