Effect of Water Vapor on the Combination and Disproportionation of Ethyl Radicals in the Gas Phase



P -. Howe, Askar Fahr, Allan H. Laufer


The role of H2O vapor on the disproportionation/combination ratio (kd/kc) of C2H5 radical reactions in the gas phase has been investigated experimentally and compared to that observed previously in aqueous solution. At added water pressures of 20 mbar (15 Torr), kd/kc ratio remains unchanged from that observed in its absence. The relationship of the invariant ratio to bonding and solvation phenomena are discussed.
