• # question_answer The following data are for the decomposition of ammonium nitrite in aqueous solution. Vol. of ${{N}_{2}}$in cc Times (min) 6.25 10 9.00 15 11.40 20 13.65 25 35.65 Infinity The order of reaction is A) zero                       B)        one                        C) two                        D)        three

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 fc calculated for different times, shows first order reaction.
