The value of Kc for the reaction:
N₂O₄(g) â†” 2NO₂ (g)
is 0.21 at 373K. If a reaction vessel at that temperatureinitially contains 0.030M NO₂ and 0.030MN₂O₄, what are the concentrations of the twogases at equilibrium? First, the reaction quotient (Q) [page 645 oftextbook] must be calculated, and then use the I.C.E table [page648-650 of the textbook] to determine the equilibriumconcentrations.
