The overall order of the reaction is ..........

(Round off to the Nearest Integer).

The reaction $A\xrightarrow{k}$ Producl, is zero order while the reaction $B\xrightarrow{k}$ Product, is first order reaction. For what initial concentration of $A$ are the half lives of two reactions equal ?
For the reaction :

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 :- 

Consider the statements $S_1$ and $S_2$:
$S_1$: Conductivity always increases with decrease in the concentration of electrolyte.
$S_2$: Molar conductivity always increases with decrease in the concentration of electrolyte.
