When the concentration of A in the reaction  $A + B$ $\rightleftharpoons$ $AB$ is doubled, the rate of reaction will be

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 $10$.

For a reaction, $I^-+OCl^-  \to IO^-+Cl^-$ in a aqueous medium, the rate of reaction is given by $\frac{{d[{IO^ - }]}}{{dt}} = k[{I^ - }][OC{l^ - }]$ The overall order of reaction is

For conversion of compound $A \rightarrow B$, the rate constant of the reaction was found to be $4.6 \times 10^{-5}\,L\, mol ^{-1}\, s ^{-1}$. The order of the reaction is $..........$ 

The rate of reaction between two reactants $A $ and $B$ decreases by a factor of $4$ if the concentration of reactant $B$ is doubled. The order of this reaction with respect to reactant $B$ is

For a chemical reaction,$ A + 2B \to C + D,$ the rate of reaction increases three times, when concentration of $A$ only is increased nine times. While when concentration of $B$ only is increased $2\,times,$ then rate of reaction also increases $2\,times$. The order of this reaction is
