$2 NO ( g )+ Cl _{2}( g ) \rightleftharpoons 2 NOCl ( s )$

This reaction was studied at $-10^{\circ} C$ and the following data was obtained

run	$[ NO ]_{0}$	$\left[ Cl _{2}\right]_{0}$	$r _{0}$
$1$	$0.10$	$0.10$	$0.18$
$2$	$0.10$	$0.20$	$0.35$
$3$	$0.20$	$0.20$	$1.40$

$[ NO ]_{0}$ and $\left[ Cl _{2}\right]_{0}$ are the initial concentrations and $r _{0}$ is the initial reaction rate.

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

(Round off to the Nearest Integer).

The rate law for the reaction  Sucrose + Water $\xrightarrow{{[{H^ + }]}}$ Glucose + Fructose is given by

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

The rate constant of the reaction $2H_2O_2(aq) \to  2H_2O(aq) + O_2(g)$ is $3\times10^{-3}\, min^{-1}$. At what concentration of $H_2O_2$, the rate of reaction will be $2\times10^{-4}\, M\, s^{-1}$ ? ............ $M$

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

Why can we not determine the order of a reaction by taking into consideration the balanced chemical equation ?
