If the rate of the reaction is equal to the rate constant, the order of the reaction is

Calculate the overall order of a reaction which has the rate expression

$(a)$ Rate $=k[ A ]^{1 / 2}[ B ]^{3 / 2}$

$(b)$ Rate $=k[ A ]^{3 / 2}[ B ]^{-1}$

The reaction that occurs in a breath analyser, a device used to determine the alcohol level in a person's blood stream is

$2 \mathrm{~K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}+8 \mathrm{H}_{2} \mathrm{SO}_{4}+3 \mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O} \rightarrow 2 \mathrm{Cr}_{2}\left(\mathrm{SO}_{4}\right)_{3}+$

$3 \mathrm{C}_{2} \mathrm{H}_{4} \mathrm{O}_{2}+2 \mathrm{~K}_{2} \mathrm{SO}_{4}+11 \mathrm{H}_{2} \mathrm{O}$

If the rate of appearance of $\mathrm{Cr}_{2}\left(\mathrm{SO}_{4}\right)_{3}$ is $2.67 \,\mathrm{~mol}$ $\min ^{-1}$ at a particular time, the rate of disappearance of $\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}$ at the same time is ...... $\mathrm{mol}\, \mathrm{min}^{-1}$ (Nearest integer)

For a reaction of order $\mathrm{n}$, the unit of the rate constant is :

For the reaction,

$2{N_2}{O_5}\, \to \,4N{O_2}\, + \,{O_2}$

the rate of reaction is

For a certain reaction, the rate $=k[A]^2[B]$, when the initial concentration of $A$ is tripled keeping concentration of $B$ constant, the initial rate would
