Classify the following reactions as being either global or elementary. For those identified as elementary, further classify them as unimolecular, bimolecular of termolecular. Give reasons for your classification:

a. CO +OH → CO2 + H

b. 2CO + O2 → 2CO2

c. H2 + O2 → H + H + O2

d. HOCO → H + CO2

e. CH4 + 2O2 → CO2 + 2H2O

f. OH + H + M → H2O + M

Answer #1

Solution :-

An elementary reaction is defined as the reaction in which the integer value is 1 with each other and a global reaction is defined as the it is the sequence of the reactions to give the overall products.

a. CO +OH → CO2 + H = elementary reaction = bimolecular

b. 2CO + O2 → 2CO2 = global reaction

c. H2 + O2 → H + H + O2 = global reaction

d. HOCO → H + CO2 = elementary reaction = unimolecular

e. CH4 + 2O2 → CO2 + 2H2O = global reaction

f. OH + H + M → H2O + M = elemetary reaction termolecular or trimolecular
