For the reaction, $2{\mathrm{SO}}_2+{\mathrm{O}}_2\rightleftharpoons 2{\mathrm{SO}}_3$, The rate of disappearance of ${\mathrm{O}}_2$ is $2\times {10}^{-4} \mathrm{mol} {\mathrm{L}}^{-1} {\mathrm{s}}^{-1}$. The rate of appearance of ${\mathrm{SO}}_3$ is

The rate of a gaseous reaction is given by the expression $\mathrm{k}\left[\mathrm{A}\right][\mathrm{B}{]}^2.$ If the volume of vessel is reduced to one half of the initial volume, the reaction rate as compared to original rate is

The value of rate constant of a pseudo-first-order reaction

If the rate constant for a first order reaction is $\mathrm{k},$ the time$\left(\mathrm{t}\right)$ required for the completion of $99\%$ of the reaction is given by

For a reaction $\mathrm{A}+2 \mathrm{B}\to$ Products, when concentration of $\mathrm{B}$ alone is increased, half life remains the same. If concentration of $\mathrm{A}$ alone is doubled, rate remains the same. The unit of rate constant for the reaction is

The rate constant of a reaction is given by $\mathrm{k}={\mathrm{PZe}}^{-\mathrm{Ea}/\mathrm{RT}}$ under standard notation In order to speed up the reaction, which of the following factors has to he decreased?

The temperature coefficient of a reaction is $2$. When the temperature is increased from $30°\mathrm{C}$ to $90°\mathrm{C}$, the rate of reaction is increased by

Higher order $\left(>3\right)$ reactions are rare due to
