If monovalent positive ion of $A,$ divalent positive ion of $B$ and trivalent positive ion of $C$ have zero electron. Then incorrect order of corresponding $I.E.$ is
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 :-
