The value of Kc for the reaction:
N2O4(g) ↔ 2NO2 (g)
is 0.21 at 373K. If a reaction vessel at that temperature
initially contains 0.030M NO2 and 0.030M
N2O4, what are the concentrations of the two
gases at equilibrium? First, the reaction quotient (Q) [page 645 of
textbook] must be calculated, and then use the I.C.E table [page
648-650 of the textbook] to determine the equilibrium
concentrations.
For the following reaction, Kc = 0.513 at 500 K. N2O4(g)⇌2NO2(g)
If a reaction vessel initially contains an N2O4 concentration of
5.50×10−2 M at 500 K, what are the equilibrium concentrations of
N2O4 and NO2 at 500 K? [N2O4], [NO2] = ____ M
For the reaction shown here, Kc = 0.513 at 500 K.

Part A
If a reaction vessel initially contains an N2O4 concentration of
5.50×10−2 M at 500 K, what are the equilibrium
concentrations of N2O4 and NO2 at 500 K?
[N2O4], [NO2] =
At a certain temperature, K for the reaction below is 7.5
L/mol.
2NO2(g) → N2O4(g)
If 2.0 moles of NO2 are placed in a 2.0 liter
container and permitted to react at this temperature, what will be
the concentration of N2O4 at equilibrium?
The equilibrium constant (KP) is 0.16 at a particular
temperature for the reaction: N2O4(g) ⇌
2NO2(g)
Given the following sets of initial conditions, what is the net
change that must occur for the reaction to reach equilibrium? Does
the reaction shift left to reach equilibrium, does the reaction
shift right to reach equilibrium or is the reaction at equilibrium
at these initial concentrations so no net change will occur?
equilibrium, left, right? PNO2 = 0.154
atm, PN2O4 = 0.148 atm...
At –80°C, K for the reaction N2O4(g) 2NO2(g) is 4.66 × 10–8. We
introduce 0.049 mole of N2O4 into a 1.0-L vessel at –80°C and let
equilibrium be established. The total pressure in the system at
equilibrium will be: (0.78 atm)
