| Initial $[A_2]$ | Initial $[B_2]$ | $R.O.R.\,(r)\,Ms^{-1}$ |
| $0.2$ | $0.2$ | $0.04$ |
| $0.1$ | $0.4$ | $0.04$ |
| $0.2$ | $0.4$ | $0.08$ |
Order of reaction with respect to $A_2$ and $B_2$ are respectively
take place in two steps :
$(a)$ $Br^{-} + H^{+} + H_2O_2 \xrightarrow{{slow}} HOBr + H_2O$
$(b)$ $HOBr + Br^{-} + H^{+} \xrightarrow{{fast}} H_2O + Br_2$
The order of the reaction is
Statement $I:$ Primary aliphatic amines react with $HNO _{2}$ to give unstable diazonium salts.
Statement $II:$ Primary aromatic amines react with $HNO _{2}$ to form diazonium salts which are stable even above $300 \,K$.
In the light of the above statements, choose the most appropriate answer from the options given below:
