Question

The following data are for the decomposition of ammonium nitrate in aqueous solution:

Volume of $N _{2}\left( cm ^{3}\right)$	Time (min)
6.25	10
9.0	15
11.42	20
13.65	25
35.02	$\infty$

The order of reaction is:

• A. Zero
• B. One
• C. Two
• D. Three

Answer 1

Answer: (B)

We find that
$\vartheta= k \left[ N _{2}\right]$
$= kV _{ N _{2}}$
$\therefore $ Order is $1$.
