Q. The following data are for the decomposition of ammonium nitrite in aqueous solution Vol. of $ {{N}_{2}} $ in cc Time (min.) 6.55 10 9.00 15 11.40 20 13.65 25 35.65 $ \infty $ The order of reaction is

Solution:

For first order reaction $ k=\frac{2.303}{t}\log \frac{a}{a-x} $ $ a\propto {{V}_{\infty }}(35.05) $ and $ x\propto {{V}_{t}} $ constant values of $ k $ calculated for different times shows first order reaction.
