Question

Which one of the following reactions is a true first-order reaction?

पर्याय

• Alkaline hydrolysis of ethyl acetate.

• Acid catalyst hydrolysis of ethyl acetate.

• Decomposition of N₂O.

• Decomposition of gaseous ammonia on a hot platinum surface.

Answer 1

Decomposition of N₂O.

Explanation:

\[\ce{N2O -> N2 + 1/2O2}\]

`"dx"/"dt" ∝ ["N"_2"O"]^1` i.e. the order of reaction = 1
