Question

A proposed mechanism for the decomposition of N2O5 is as follows:
N2O5 NO2+ NO3 slow step
NO2+ NO3 NO2+ O2+ NO fast step
NO + N2O5 3NO2 fast step
What is the overall chemical equation predicted by this mechanism?
A) N2O5+ NO2+ NO3 → 4NO2+ O2
B) N2O5+ NO →3NO2
C) 2N2O5→4NO2+ O2
D) N2O5→NO2+ NO3
E) N2O5→NO2+ O2+ NO
