In an elementary reaction: $2\mathrm{A}+\mathrm{B}\stackrel{}{\to } \mathrm{C}+\mathrm{D},$ the molecularity of the reaction is _____.

$75\%$ of a first order reaction was completed in $32$ minutes. $50\%$ of the reaction will be completed in.

The half-life of a radioactive element is $1580$ years. How long will it take to reduce to $1/4^{\mathrm{th}}$ of its original mass?

Analyse the given graph, drawn between the concentration of reactant vs. time.

Predict the order of the reaction.

The temperature coefficient of most of the reactions lies between:

In the reaction ${\mathrm{BrO}}_3^{-}\left(\mathrm{aq}\right)+5{\mathrm{Br}}^{-}+6{\mathrm{H}}^{+}\to 3{\mathrm{Br}}_2+3{\mathrm{H}}_2\mathrm{O}$ the rate of appearance of bromine is related to the rate of disappearance of bromide ions as
 

For the reaction ${\mathrm{N}}_2{\mathrm{O}}_5\left(\mathrm{g}\right)\to 2{\mathrm{NO}}_2\left(\mathrm{g}\right)+\frac{1}{2}{\mathrm{O}}_2\left(\mathrm{g}\right)$ the value of rate of disappearance of ${\mathrm{N}}_2{\mathrm{O}}_5$ is given as $6.25\times {10}^{-3} \mathrm{mol} {\mathrm{L}}^{-1} {\mathrm{s}}^{-1}$. The rate of formation of ${\mathrm{NO}}_2$ and ${\mathrm{O}}_2$ is given respectively as :

The decomposition of ${\mathrm{N}}_2{\mathrm{O}}_5$ in ${\mathrm{CCl}}_4$, at $318 \mathrm{K}$ is studied by monitoring the concentration of ${\mathrm{N}}_2{\mathrm{O}}_5$ in the solution. Initially the concentration of ${\mathrm{N}}_2{\mathrm{O}}_5$ is $2.4 \mathrm{mol} {\mathrm{L}}^{-1}$ and after $200$ minutes, it is reduced to $2.00 \mathrm{mol} {\mathrm{L}}^{-1}$. What is the rate of production of ${\mathrm{NO}}_2$ during this period in $\mathrm{mol} {\mathrm{L}}^{-1} {\min }^{-1}$?
