Consider the reaction between chlorine and nitric oxide

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

On doubling the concentration of both reactants, the rate of the reaction increases by a factor of $8 .$ However, if only the concentration of $C l_{2}$ is doubled, the rate increases by a factor of $2 .$ The order of this reaction with respect to $NO$ is :

For the reaction : $2A + B \to  A_2B$ ; the rate $= K[A]\, [B]^2$ with $K = 2.0\times10^{-6}\, lit^2\, mol^{-2}\, sec^{-1}$. Initial concentration of $A$ and $B$ are $0.2\, mol/lit$ and $0.4\, mol/lit$ respectively. Calculate the rate of reaction after $[A]$ is reduced to $0.12\, mol/litre$.

Which of the following reaction will have fractional order for $A_2$ or $B_2$ ?

For the reaction $A \to B$, the rate increases by a factor of $2.25 $ when the concentration of $A$ is increased by $ 1.5$. What is the order of the reaction

$A + 2B \to C$, the rate equation for this reaction is given as Rate $= K[A][B]$ . If the concentration of $A$ is kept the same but that of $B$ is doubled what will happen to the rate it self ?

The decomposition of $NH _{3}$ on $Pt$ surface is a zero order reaction. If the value of rate constant is $2 \times 10^{-4}\,mole $ $liter^{-1}\, sec ^{-1}$ The rate of appearance of $N _{2}$ and $H _{2}$ are respectively.
