Nitrogen dioxide gas, NO2(g), can
be reach equilibrium with dinitrogen
tetroxide gas, N2O4
(g), in a closed system. At 1.0 atmosphere,
the boiling point N2O4
is 21oC. the equation below
represents this system.
2NO2(g) <=> N2O4(g)
+ Energy

58 Compare the rate of the
forward reaction to the rate of
the reverse reaction when the
system is at equilibrium.
| Answer-->the rates
are equal |
59 State how the
equilibrium shifts when the
pressure on the equilibrium
system is increased at constant
temperature.
| Answer-->
shifts right
shifts to
theside with less moles of
gases |
60 Compare the
entropy of a sample of
dinitrogen tetroxide gas at 25oC
and 1.0 atmosphere to the
entropy of the sample of
dinitrogen tetroxide liquid at
15oC and 1.0
atmosphere.
| Answer-->the gas has
a higher entropy than the
liquid
or the liquid has a
lower entropy than the gas |
