Answer #1

Let x be the change in concentration to reach equilibrium.

Hence, At equilibrium:

[N2O4] = initial concentration - change in concentration = 5.5 x 10-2 - X

[NO2] = initial concentration + change in concentration = 0 + 2X

Hence, equilibrium constant expression will be given by:

Solving for x we get:

Therefore, Equilibrium concentrations will be:
