The competitive reactions of Br atoms with CH, and CD, were studied over the temperature range of 562' to 637ยฐK. Over this temperature interval, the kinetic isotope effect, k,/k,, varied from 3.05 to 2.47 for the reactions Br + CH, -% HBr + CH, The rate constant ratio k,/k, , expressed in Arrhenius
The k/ak isotope effect for addition of ArSCl to R-methylstyrene is small and unchanged by addition of LiClO ; k/'k is high and unchanged. k/Bk values are liigh and uncha:ged, while k/'k increases from For styrene and R-chlorostyrene -1.025 to -1.04. R-Methyl-
