The experimental data for the reaction $2A + {B_2} \to 2AB$ isThe rate equation for the above data is

Exp.	$[A]_0$	$[B]_0$	Rate (mole $s^{-1}$)
$(1)$	$0.50$	$0.50$	$1.6 \times {10^{ - 4}}$
$(2)$	$0.50$	$1.00$	$3.2 \times {10^{ - 4}}$
$(3)$	$1.00$	$1.00$	$3.2 \times {10^4}$

In the reaction $A + B \to $ Products, if $B$ is taken in excess, then it is an example of

The instantaneous rate of disappearance of $MnO_4^-$ ion in the following reaction is $4.56\times10^{-3}\,Ms^{-1}$,  $2MnO_4^-+ 10I^-+ 16 H^+ \to  2 Mn^{2+} + 5I_2 + 8H_2O$ The rate of appearance $I_2$ is
