If doubling the initial concentration of reactant doubles $t_{1/2}$ of reaction, the order of reaction is

$A_2 + 2\,B \to 2\,AB$

Order of reaction w.r.t. $A_2$ and $B$ are respectively

For the first order decompsition reaction of $N_2O_5$, it is found that - 

$(a)$   $2N_2O_5\rightarrow\,\,4NO_2(g)+O_2(g)-\frac{d[N_2O_5]}{dt}=k[N_2O_5]$

$(a)$   $N_2O_5\rightarrow\,\,2NO_2(g)+1/2\,\,O_2(g)-\frac{d[N_2O_5]}{dt}=k'[N_2O_5]$

which of the following is true ?

Reaction : $KCl{O_3} + 6FeS{O_4} + 3{H_2}S{O_4} \to $ $KCl + 3F{e_2}{\left( {S{O_4}} \right)_3} + 3{H_2}O$

Which is True $(T)$ and False $(F)$ in the following sentence ?

The order of this reaction is $2$.

Write differential rate expression of following reaction and give its order of reaction:

$CHCl _{3}+ Cl _{2} \rightarrow CCl _{4}+ HCl$

$CH _{3} COOC _{2} H _{5}+ H _{2} O \rightarrow CH _{3} COOH + C_2H_5OH$

For a reaction between $A$ and $B$ the order with respect to $A$ is $2$ and the other with respect to $B$ is $3.$ The concentrations of both $A$ and $B$ are doubled, the rate will increase by a factor of
