Equilibrium And Concentration Gizmo Answers Quizlet File

[NO2] = 0.50 M [N2O4] = 1.50 M

The reaction quotient (Q) equals the equilibrium constant (K):

As the reaction proceeds, NO2 molecules collide and react to form N2O4 molecules. The concentration of NO2 decreases, and the concentration of N2O4 increases.

Q = [N2O4] / [NO2]^2 = 0.00 / (1.00)^2 = 0.00 equilibrium and concentration gizmo answers quizlet

The reaction has reached equilibrium.

Q = [N2O4] / [NO2]^2 = 1.33 / (0.67)^2 = 2.96

2NO2(g) ⇌ N2O4(g)

Q = [N2O4] / [NO2]^2 = 1.00 / (1.00)^2 = 1.00

Suppose we add 1.00 M of N2O4 to the container. The new concentrations are:

The reaction is approaching equilibrium. [NO2] = 0

[NO2] = 0.67 M [N2O4] = 1.33 M

At some point, the reaction reaches equilibrium, where the rates of forward and reverse reactions are equal. The concentrations of NO2 and N2O4 no longer change.
