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).

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.
