Rate constant ratios, k d /k c , for the disproportionation/combination reaction at a temperature of 295 Ϯ 2 K, have been measured as 0.034 Ϯ 0.009 for the collision between CF 3 CH 2 CF 2 ϩ CF 3 radicals and as 0.075 Ϯ 0.019 for CF 3 CH 2 CF 2 ϩ CF 3 CH 2 CF 2 radicals. The effect of the two fluori
