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.

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)
