As we learnt

 

Gay Lussac's law of Gaseous Volumes -

When gases combine or are poduced in a chemical reaction, they do so in a simple ratio by volume provided all gases are at the same temperature and pressure.

- wherein

H_{2}}_{(g)} + {O_{2}}_{(g)} \rightarrow {H_{2}O}_{(g)}

100 ml        50ml            100ml

 

 

N_{2} + 3H_{2} \rightarrow 2NH_{3}

22.4      x                0

By Gay Lussac's Law:

x = 3\times 22.4 = 67.2L

\therefore Solution is B
