Order of a reaction can have

Consider a reaction $\mathrm{aG}+\mathrm{bH} \rightarrow$ Products. When concentration of both the reactants $\mathrm{G}$ and $\mathrm{H}$ is doubled, the rate increases by eight times. However, when concentration of $\mathrm{G}$ is doubled keeping the concentration of $\mathrm{H}$ fixed, the rate is doubled. The overall order of the reaction is

The three experimental data for determine the differential rate of reaction $2 NO _{( g )}+ Cl _{2( g )} \rightarrow 2 NOCl_{( g )}$ at definate temperature. are given below.

$(a)$ Calculate order of reaction.

$(b)$ Calculate value of rate constant.

Write differential rate expression of following reaction and give its order of reaction :

$2 HI \rightarrow H _{2}+ I _{2}$

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

For a chemical reaction $A \to B$ it is found that the rate of reaction doubles, when the concentration of $A$ is increased four times. The order in $A$  for this reaction is

The following data was obtained for chemical reaction given below at $975\, \mathrm{~K}$.

$2 \mathrm{NO}_{(\mathrm{g})}+2 \mathrm{H}_{2(\mathrm{~g})} \rightarrow \mathrm{N}_{2(\mathrm{~g})}+2 \mathrm{H}_{2} \mathrm{O}_{(\mathrm{g})}$

The order of the reaction with respect to $\mathrm{NO}$ is ..... .
