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?
