A) No PbBr₂(s) will precipitate because Q_spsp.
B) No PbBr₂(s) will precipitate because Q_sp>K_sp.
C) PbBr₂ can only be formed from the reaction of Pb(s) with Br₂(l) .
D) A precipitate of PbBr₂(s) will form because Q_sp>K_sp.
E) Insufficient data is given to make a prediction about whether a precipitate will form or not.
