The lowest total pressure p at which the miXture

Hg in glass vessels of 6.56 and 1,83 cm diameter.
Filaments of other solids, 0.05-0,1 cm In diameter,
raise p. The greatest Increase was observed wiLih
Z Cr2O4 and graphite; both give p = 10.3 mm in
a weasel that, alone, gave p " 0,53 at 490?, Au,
U, Pt, and stainless steel show smaller increases
of p. Untreated quartz raised p at 440, from
0.94 to 2.34, and quartz rinsed with BY raised p
to 1.48. NCl did not affect p at 500? because of
rapid sraporation. Pd and (above 390?) Pt
catalyzed the combustion of E12 so that p could
not be measured. From the experimental p values of
the coefficient 6 of recombination of E atoms at

graphite have g e 1.0 at 490?, An 0.098 at 4400,

pyrex glass washed with a HpB407 solution 0.00002
at 440?. The pressure p in the presence of graphite
was determined also at 5300 and 5580; from these
values the eaebgy of activation of the reaction
H+ 02 ^ 03+O appears to be 17,800 calories,
From the increase of the upper limit of Ignition
with temperature betweeu 310? and 410? in a glass

Mixtures of 2 32 + 02 in a quartz tube were irradiated

photochemical reaction is complicated by the dark
reaction, the rate of which increases linearly
with tetperature. At a ccastant Jroesnre (20 mm)
the ignition temperature in the darkness Is 4180,
and is lowered by the strongest illumination used

The asobanlsa of the ooabustion of H2 postulated
by Levi. and Elbe is supplemented by the reaction
AD24-UgO : R2O2+ OH. This reaction accounts for
the acceleration of combustion caused by H2O after
a latont period and the absence of the acceleration

of 102 is negligible. Calouletion shows that,

the oorditSons (temperature and pressure) giving

A method is devised to shoe that a solid can accelerate

If the reaction takes place on the catalyst surface,
the tesperature of the euxperiannt (b) shoull be

both readings should be identical. The identity

ZtCI. At constant temperature and pressure, T
depends on the composition of the alloy (39-58
atmospheric % of Na) and shove a minimum at 50
atmospheric % Na. Hence, it is possible to detect
the compound PbNa by kinetic measurements. I- is
greater the smaller the pressure; e.g., at 200 in
the presence of Pblia 1' is 5 hours at 80, and 1.5
boars at 800 mm as. On a temperature rise, I- first
decreases (e.g., from 3 hours at 200 to 0.6 hour at
350) and then suddenly becomes very great. The
temperature T at which the rapid increase of 7-
takes place is independent of the compound of the
alloy and increases with the pressure of StCl from,
e.g., 200 at 100 and 580 at 1,600 mm I1g. Probably,
the reaction has a chain mechanism, the breaking of
chains; has a greater temperature coefficient than
the chain formation, and at T the rates of formation
and breaking become equal.

The amaint of NO formed in the explosion of mixtures
of F.2-02-N2, w?-ging from 2896 to 4896 B2i and C2B4-02-
N2i containing 6-896 C284, was maximna halfway
between zero coneentratiano of N2 and excess 02 over
the requirement for complete oxidation. 30 yield
was determined after explosion for mixtures of

d B2 with N2 equal to excrss 02, -air, (goo C0-
1 R2) -O ft with N2 equal to excess 00, and
(90 00-1~ N2)-air at 200?. pressure and initial
te?perature from -160? to 3200. The equili lam
constant C? in the equation, [HO] a C, Lb-.j VP0 where (oJ is the excess 0 after combustion, is indepen-
dent of he N2 and 0 concentrations but is propor-
tional to the.oonbuetib)e in the mis&ure. For the
above experiments the curves of C' plotted as a
function of the heat of combustion plus a correction
for the sensible heat of the mixture coincide.
The observed yields are 60-70% of the calculated
thermodynamic egatliariun if the explosion teapers-
tare is corrected for the. Macho affect for noohoxc-
geoecus temperature distribution due to the tine
effect involved in the propagation of flame. A
mixture of'coal Qae'02-air was burned in a special
iaspirator, Venturi-typeburner with an estimated
[saperatars of 2,435? I. Samples of the gas at a
series, of. points starting from the throat of the
burner shoved an inaroase in NO concentrations
up to a'm-zisna. The results confirm the thermal
formation of ls0 from l2 and 02 as a result of the
htgh tempsratinreproduced' on otidationof the
aamauetible. The'amonnt- ofNO on.expioeibn3 of
aixtayes of '2$ 32-38 02-38% a2 at 2C 'o a,
with addition of varying amounts of n0 up to 10
ma, was determined. Aotivatioc energies of 86 aM
129 kg-cal per soleonlar were found for the heat
of leeo position and fornation, reryeotively.
The dependence of the reaction velocity on 02
concentration predicted 'y the chain mechanism
was oonfirme4 by experiz sAts with ezse ss fuel.
The expression o~ NO)JI a USX 10"/l[0,3)

The eqrilibrium constant I for the rerotion AcON +
ltp8 a bolt + 820 in liquid phase man be calculated
from the egailibriun in the vapor phase and the
vapor pressure of the constituents. The equili-
brium. in the vapor at 45-750 corresponds to 92% AoOSt.
and the egailibriaa constant is 300,; at 45? and 196
at 7'30. The aorr.ction for the association of
AoOK, made by Falford and Brundage, when oaloalat-
ing this constant is wrong. The calculated value
of.I doai not agree with the eaperieCntal,
prsesmnb'.y beoamse the liquid is not an ideal
ailitsre. The equilibrium in the presence of multi-
saleoulaz adsor$ion layers must depend on the
relative volumes of the gas phase and the adsorbed
L.yere.

A stream of O vapor passed through a discharge tube
in which OH rmed was then mixed with a 00 stream,
and passed a heated reaction tube and then a receiver
pooled with liquid,ajr. The concentration of OR in
the reaction tube was deterained spectroscopically
in th? "so,nos asd the presence of 00; the difference
gave the amount of (l3' hick re?;oted with CO to give
CO2 and 1. The reaction oonstant for the
disappearance ofo was 1.1 z lO fTexp (-5000%')
co/sea between T -- 75? and T - 2470. The rate of
raeotioadetemined from the amount of CO2. condensed
in the receiver was wash greater. It was shown that
the $2O.sapor, afte7r thosdisaharge tube, contained
atomic 0 and the seactioa`of 0 with CO was the nain
worse of COQ.
