The decomposition of an aqeous solution ...

The decomposition of an aqeous solution of ammonium nitrite was studied. The volume of nitrogen gas collected at
`{:("Time (minutes)",10,15,20,oo),("Vol.of N"_(2)(mL)",6.25,9.00,11.40,35.05):}`
From the above data prove that the reaction is of the first order.

Text Solution

Verified by Experts

`[A]_(0)` = volume of nitrogen at `pp=35.05`
` [A]_(t)=V_(oo)-V_(t)`
when t=10 `w.k=(2.303)/(10)log. (35.05)/((35.05-6.25))=0.0196`
when t=15 k= 0.0198
when t=20 k=0.0196
