The plot of $$t_{1 / 2} \mathrm{~v} / \mathrm{s}~[R]_0$$ for a reaction is a straight-line parallel to $$X$$-axis. The unit for the rate constant of this reaction is

$$\mathrm{mol} \mathrm{~L}^{-1} \mathrm{~s}$$

$$\mathrm{mol~L}^{-1} \mathrm{~s}^{-1}$$

$$\mathrm{L} \mathrm{~mol}^{-1} \mathrm{~s}^{1-}$$

Which is a wrong statement?

Rate constant $$k=$$ Arrhenius constant $$A$$ : if $$E_a=0$$

$$e^{-E_a / R T}$$ gives the fraction of reactant molecules that are activated at the given temperature

In $$k v s \frac{1}{T}$$ plot is a straight line

presence of catalyst will not alter the value of $$E_a$$

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

$2 \times 10^{-4} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}$

$4 \times 10^{-4} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}$

$1 \times 10^{-1} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}$

$6 \times 10^{-4} \mathrm{molLL}^{-1} \mathrm{~s}^{-1}$
