Q. Decomposition of $NH _{4} NO _{2}($ aq $)$ into $N _{2}$ (g) and $2 H _{2} O ( l )$ is first order reaction. Which of the following graph is correct?

Chemical Kinetics

Solution:

$A_{t}=A_{0} e ^{-k t}$ where $A_{t}=(a-x)=$ conc. of reactant remained after time $=t$
$A_{0}=a=$ Initial concentration of reactant when $t=0$
