When lead (IV) oxide is heated above 300°C it decomposes according to the following reaction PbO₂(s) ⇋ PbO(s) + O₂(g). Consider the two sealed vessels of PbO₂
shown here. If both vessels are heated to 400°C and allowed to come to equilibitum which of the following statements is true?

(a) There will be less PbO₂ remaining in vessel A

(b) There will be less PbO₂ remaining in vessel B

(c) The amount of PbO₂ remaining in each vessel will be the same.
