Several attempts have been made to correlate the disproportionation and the combination rate constant ratio, k,/k,, of the alkyl radicals with the entropy change of the processes [ 1-31. Bradley [I] made a specific suggestion that the k,/k, ratio is a function of the entropy change of the processes
The disproportionation-combination reactions of radicals 4,4-dimethylpentyl-2 and 2,4-dimethylpentyl-2, produced by collisional stabilization of the respective chemically activated species, have been studied at 298"K, with and without getter radicals. Use of getters t-C4H9 and CzHs with 4,4-dimethyl
A new determination of the disproportionation/cornbination ratio for C2Fs and CZH, radicals gives a value of A(C2F,, C2H,) = 0.24 5 0.02, independent of temperature. The cross-combination ratio for the two radicals was found to increase with temperature and the significance of this is discussed in e
Cross-disproportionation to combination ratios for CF2H and n-C3H7 radicals have been determined (the hydrogen acceptor radical is given first) to be A(n-C3H7,CF2H) = 0.30 2 0.01 and A(CF2H, n-C3H7) = 0.057 ? 0.006.
