8. The thermal decomposition of nitric oxide at elevated temperatures
2NO → N₂+02
has been studied in a batch reactor where at temperatures below 2000K the rate
expression that applies to low conversions is:
r = kCm05 Co
At high conversions, or when the initial mixture contains a high concentration of O2 the
rate expression is given by:
r = k' Cм0.5 C15C0,5
To explain these kinetics the following chain reaction mechanism has been proposed:
Initiation:
Propagation:
2NON₂O +0
k₂
E1=272.0 kJ/mol
0+ NO O₂+ N
E₂-161.0 kJ/mol
N+NO N₂+0
E3-1.4 kJ/mol
K4
20+ MO₂+M
E4=14.0 kJ/mol
ks
Termination:
where M is any molecule capable of the energy transfer necessary to stabilize the oxygen
molecule.
Once appreciable amounts of O2 are present in the reaction mixture, the initiation
reaction that is the primary source of atomic oxygen is no longer the first reaction.
Instead, the following reaction begins to dominate the chain initiation process:
Initiation (high O2):
