why decomposition of N2O on AU is first order?

Dear student,

Nitrous oxide is most commonly prepared by careful heating of ammonium nitrate, which decomposes into nitrous oxide and water vapor.The addition of various phosphates favors formation of a purer gas at slightly lower temperatures.

NH₄NO₃ (s) → 2 H₂O (g) + N₂O (g)
