14.Order of reaction of N2O5→2N2O5+ O2

Explanation

The correct answer for the order of the reaction N2O5 → 2N2O5 + O2 is:(a) First orderHere's why the other options are incorrect:(b) Second order: While the decomposition of N2O5 might initially appear to be second order as it involves one N2O5 molecule reacting with another, further analysis reveals that this reaction likely proceeds through a single-step mechanism where only one N2O5 molecule is involved in the rate-determining step.(c) Third order: Similarly, there's no evidence for a third-order reaction mechanism in this case. The rate primarily depends on the concentration of N2O5 itself, indicating a first-order dependency.(d) Zero order: A zero-order reaction implies that the rate is independent of the concentration of the reactant. This isn't true for the decomposition of N2O5, as its rate directly depends on its concentration.
