?When lead(IV) oxide is heated above \(300^{\circ} \mathrm{C}\), it decomposes according
Chapter 15, Problem 15.7(choose chapter or problem)
When lead(IV) oxide is heated above \(300^{\circ} \mathrm{C}\), it decomposes according to the following reaction \(\mathrm{PbO}_{2}(s) \rightleftharpoons \mathrm{PbO}(s)+\mathrm{O}_{2}(g)\). Consider the two sealed vessels of \(\mathrm{PbO}_{2}\) shown here. If both vessels are heated to \(400^{\circ} \mathrm{C}\) and allowed to come to equilibrium, which of the following statements is true?
(a) There will be less \(\mathrm{PbO}_{2}\) remaining in vessel A,
(b) There will be less \(\mathrm{PbO}_{2}\) remaining in vessel B,
(c) The amount of \(\mathrm{PbO}_{2}\) remaining in each vessel will be the same. [Section 15.4]
