Multiple Choice
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
