Consider the decomposition equilibrium for dinitrogen pentoxide:
2N2O5(g) ⇌ 4NO2(g) + O2(g)
At a certain temperature and a total pressure of 1.00 atm, the N2O5 is 0.50% decomposed (by moles) at equilibrium.
a. If the volume is increased by a factor of 10.0, will the mole percent of N2O5 decomposed at equilibrium be greater than, less than, or equal to 0.50%? Explain your answer.
b. Calculate the mole percent of N2O5 that will be decomposed at equilibrium if the volume is increased by a factor of 10.0.
