Statement $I : C _{2} H _{5} OH$ and $AgCN$ both can generate nucleophile.
Statement $II : KCN$ and $AgCN$ both will generate nitrile nucleophile with all reaction conditions.
Choose the most appropriate option :
Half-life does not depend on the concentration of the reactant. After $10 \,\min,$ volume of $N_2$ gas is $20\, L$ and after the completion of reaction, it is $100\, L$. Hence, rate constant is :-
