When N₂O₅ is heated at certain temperature, it dissociates as:

N₂O₅(g) N₂O₃ g + O₂(g); K_c = 2.5
At the same time, N₂O₃ also decomposes as:
N₂O₃(g) N₂O g + O₂ (g)

If initially 4.0 moles of N₂O₅ are taken in 1.0 litre flask and allowed to dissociate and concentration of O₂ at equilibrium is 2.5 M. Equilibrium concentration of N₂O₅ is:

1.0 M

1.5 M

2.166 M

1.846 M
