For the thermal decomposition of N2O5 the following data are obtained at 45C:

The decomposition reaction to consider is:

N₂O₅(g) -> N₂O₄(g) + O₂(g)

Determine the partial pressure of N2O5. 

If PX is the partial pressure associated with the moles of reactant that have reacted at each time and the partial pressure of the reactant is initially 348.4 mm Hg:

a.Determine the partial pressure of N2O5 after 10 minutes.
