MCQ
Which of the following equilibrium is not shifted by increase in the pressure
  • ${H_2}_{(g)} + {I_2}_{(g)}$ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ $2H{I_{(g)}}$
  • B
    ${N_{2(g)}} + 3{H_{2(g)}}$ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ $2N{H_3}_{(g)}$
  • C
    $2C{O_{(g)}} + {O_2}_{(g)}$ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ $2C{O_2}_{(g)}$
  • D
    $2{C_{(S)}} + {O_{2(g)}}$ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ $2C{O_{(g)}}$

Answer

Correct option: A.
${H_2}_{(g)} + {I_2}_{(g)}$ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ $2H{I_{(g)}}$
(a) $\mathop {{H_{2(g)}} + {I_{2(g)}}}\limits_2 $ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ $\mathop {2HI}\limits_2 $
