The elementary reaction $2SO_2(g) + O_2(g) \to 2SO_3(g)$ is carried out in $1\, dm^3$ vessel and $2\,dm^3$ vessel separately. The ratio of the reaction velocities will be

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

For a reaction $2A + B \to $ Products, doubling the initial concentration of both the reactants increases the rate by a factor of $8$, and doubling the concentration of $+B$  alone doubles the rate. The rate law for the reaction is

Explain order of reaction of complex reaction by giving examples.

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 chemical reaction....can never be a fraction
