Solution

The correct option is D $0.2$
${N_{2}}_{(g)} + {3 H_{2}}_{(g)} ⇋ {2 N H_{3}}_{(g)}$

Given that when the equilibrium is reached, it is found that a half mole of $N_{2}$ is used up, i.e.,
Amount of $N_{2}$ used $= 0.5 moles$

$∴$ Amount of $N H_{3}$ produced by 1 mole of $N_{2} = 2 moles$

$\Rightarrow$ Amount of $N H_{3}$ produced by 0.5 mole of $N_{2} = 1 mole$

Volume of vessel $= 5 L$

Equillibrium concentration of $N H_{3} = \frac{No. of moles}{Volume} = \frac{1}{5} = 0.2 moles$

Hence, option $C$ is correct.
