Physical Chemistry> For the reaction, N 2 O 5 (g) = 2NO 2 (g)...

For the reaction, N2O5(g) = 2NO2(g) + 0.5 O2(g), calculate the mole fraction of N2O5(g) decomposed at constant volume temperature, if the initial pressure is 600 mm Hg and the pressure at any time is 960 mm Hg. Assume ideal gas behavior.

N₂O_5(g) ⇌ 2NO_2(g) + 1/2 O_2(g)

Initial pressure 600 0 0

Final pressure 600 – P 2P P/2

P ∝ moles when V and T are constant

(where moles equivalent to pressure –P are decomposed)

Total pressure = 600 – P + 2 P + P/2 = 960 mm of Hg

∴ P = 240 mm Hg

Thus moles of N₂O₅ decomposed = 240/600 = 0.4
