For the reaction between $A$ and $B$ , the initial rate of reaction $(r_0)$ was measured for different initial concentration of $A$ and $B$ as given below Order of the reaction with respect to $A$ and $B$ respectively, is $\sqrt 2  = 1.4 ,\,\sqrt 3  \times 10^{-4}$ 

$A/mol\,L^{-1}$	$0.2$	$0.2$	$0.4$
$B/mol\,L^{-1}$	$0.3$	$0.1$	$0.05$
$r_0/mol^{-1}s^{-1}$	$5.0\times 10^{-5}$	$5.0\times 10^{-5}$	$1.4\times 10^{-4}$

The rate of the reaction becomes twice when the concentration of reactant becomes $8$ times then the order of the reaction is

The rate of dissappearance of $MnO_4^-$ in the following reaction is $4.56 \times 10^{-3}\, M/s$

$2MnO_4^-+ 10I^-+ 16H^+ \to 2Mn^{2+} + 5I_2 + 8 H_2O$

The rate of apperance of $I_2$ is

If in a certain reaction, two different reactants take part then

Select the rate law that corresponds to the data shown for the following reaction $A+ B\to C$

The rate law of the reaction $A + 2B \to $Product is given by $\frac{{d[dB]}}{{dt}} = k[{B^2}]$. If $ A$  is taken in excess, the order of the reaction will be
