Question

2Pb(NO3)2 (s) = 2PbO(s) + 4NO2 (g) + O2 (g)

a) If oxygen is added to the system at equilibrium, how will the concentration of nitrogen be affected? Why?

b) How will the amount of lead (II) nitrate in the container be affected by the removal of oxygen? Why?

c) How will the addition of lead (II) oxide to the system at equilibrium affect the equilibrium concentration of nitrogen dioxide? Why?

d) This system is endothermic, what effect would an increase in temperature have on the rate of the forward reaction? Would the equilibrium constant increase or decrease?

Explanation / Answer

2Pb(NO3)2 (s) = 2PbO(s) + 4NO2 (g) + O2 (g) a) If oxygen is added to the system
