MCQ
The paramagnetic molecule at ground state among the following is
- A${H_2}$
- ✓${O_2}$
- C${N_2}$
- D$CO$
${O_2} \to {(\sigma 1s)^2}{({\sigma ^*}1s)^2}{(\sigma 2s)^2}{({\sigma ^*}2s)^2}{({\sigma ^*}2p_z)^2}$
$(\pi 2p_x^2 \equiv \pi 2p_y^2)\;({\pi ^*}2p_x^1 \equiv {\pi ^*}2p_y^1)$

$(B)$ $I _{2}+ H _{2} O _{2}+2 OH ^{-} \rightarrow 2 I ^{-}+2 H _{2} O + O _{2}$
Choose the correct option.
$NH_3{_{(g)}}\ \rightleftharpoons \ \frac {1}{2} {N_2}_{(g)} + \frac {3}{2} {H_2}_{(g)}$ ; $K_P$
The degree of dissociation $(\alpha )$ of $NH_3$ is related to total equilibrium pressure $(P^o )$ as
