Chemistry question - is it at equilibrium? If not which way does it shift?

The following reaction: 2Pb(NO3)2(s) ⇌ 2PbO(s) + 4NO2(g) + O2(g) has an equilibrium equal to 0.23 M^5. During the reaction the chemist measures the reactants and the products and gets 10 grams of Pb(NO3)2, 2.02g of PbO, 0.25 M NO2, and 0.220 M O2, is it at equilibrium? If not which way does it shift?
