Select incorrect statement about $N_2{O}_4$ :

Q. Of the following statements which are true for $N{O}_2$?
$i)$ Nitrogen dioxide brown liquid turns pale on cooling and becomes colourless solid
ii) $N{O}_2$ undergoes dimerisation to form $N_2{O}_4$
iii) $N{O}_2$ is paramagnetic, $N_2{O}_4$ is diamagnetic

Q. In a closed container, $N{O}_2$ was taken which dimerises to give $N_2{O}_4$. After some time, mole fraction of $N_2{O}_4$ was found to be $\frac{2}{3}$ in the container. Calculate the $\%$ dimerisation of $N{O}_2$?

Q. Which of the following is/are paramagnetic?

Q. Out of $NO,N{O}_2,N_{2}O,N_2{O}_4$ and $N_2{O}_2$, the paramagnetic species are__________.

Q. Consider a system containing $N{O}_2$ and $S{O}_2$ in which $N{O}_2$ is consumed in the following two parallel reactions: $2N{O}_2\stackrel{k_1}{\to }{N}_2{O}_4$ and $N{O}_2+S{O}_2\stackrel{k_2}{\to }NO+S{O}_3$. The rate of disappearance of $N{O}_2$ will be equal to:
