Question

Gaseous nitrogen dioxide forms dinitrogen tetroxide according to this equation:
2NO₂(g) ⇌ N₂ O₄(g)
When 0.10 mol NO₂ is added to a 1.0-L flask at 25 °C, the concentration changes so that at equilibrium,
[NO₂] = 0.016 M and [N₂O₄] = 0.042 M.
(a) What is the value of the reaction quotient before any reaction occurs?
(b) What is the value of the equilibrium constant for the reaction?
