Abstract
The reaction of atomic oxygen with hydrogen sulphide has been analyzed in terms of the following reaction mechanism. O+H2S→OH+SH; k1= 1.37 × 10–14 cm3 molecule–1 s–1(1) O+OH→H+O2; k2= 4.3 × 10–11 cm3 molecule–1 s–1(2) H+H2S→H2+SH; k3= 3.20 × 10–12 cm3 molecule–1 s–1(3) SH+O→H+SO; k4= 5.0 × 10–10 cm3 molecule–1 s–1(4) SH+H→S+H2; k5= 1.3 × 10–10 cm3 molecule–1 s–1(5) SO+OH→SO2+H; k6= 1.17 × 10–10 cm3 molecule–1 s–1(6) S+O2→SO+O; k7= 1.2 × 10–12 cm3 molecule–1 s–1. (7) Numerical integration of the above rate equations yielded reaction profiles for O, H, and SO that accurately reproduced those measured experimentally in a fast discharge flow system using e.s.r. detection. The consistency of the mechanism with known reactions of sulphur-containing species is discussed.Keywords
