29. Consider the decomposition of lead(IV) oxide: PbO2(s) PbO(s) + O2(g) At a certain temperature, the equilibrium constant for this reaction is K,= 0.20. If you place a large amount of PbO2(s) is a sealed container kept at this temperature, what will be the partial pressure of O2(g) once the system reaches equilibrium?

Transcribed Image Text:29. Consider the decomposition of lead(IV) oxide:
PbO2(s)
- PbO(s) + O>(g)
At a certain temperature, the equilibrium constant for this reaction is K,, = 0.20. If
you place a large amount of P6O2(s) is a sealed container kept at this temperature,
what will be the partial pressure of O2(g) once the system reaches equilibrium?
O (A) 0.020 atm
(B) 0.20 atm
O (C) 0.10 atm
(D) 0.010 atm
Activa
O (E) 2.0 atm

Transcribed Image Text:28. The reaction 2 CO2(g)=2 C0(g)+O2(g) is known to be endothermic. According to
Le Chatelier's principle, how will this reaction's equilibrium be affected, if the
reaction temperature is increased?
O (A) The equilibrium constant will decrease and the reaction will shift to the left.
(B) The equilibrium constant will be unchanged, but the reaction will shift to the
left.
(C) The equilibrium constant will increase and the reaction will shift to the right.
(D) The equilibrium constant will be unchanged, but the reaction will shift to the
right.
(E) The equilibrium concentrations will not be affected.
