Which of the following equilibria will shift to right side on increasing the temperature

A
$C{O_{(g)}} + {H_2}{O_{(g)}}$ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ $C{O_2}_{(g)} + {H_2}_{(g)}$
B
$2S{O_2}_{(g)} + {O_2}_{(g)}$ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ $2S{O_3}_{(g)}$
✓
${H_2}{O_{(g)}}$ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ ${H_2}_{(g)} + \frac{1}{2}{({O_2})_{(g)}}$
D
$4HC{l_{(g)}} + {O_2}_{(g)}$ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ $2{H_2}{O_{(g)}} + 2C{l_2}_{(g)}$

Answer

Correct option: C.

${H_2}{O_{(g)}}$ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ ${H_2}_{(g)} + \frac{1}{2}{({O_2})_{(g)}}$

(c) ${H_2}O_{(g)}$ $PC{l_5}_{(g)} \rightleftharpoons PC{l_3}_{(g)} + C{l_2}_{(g)}$ ${H_{2(g)}} + \frac{1}{2}{O_{2(g)}}$

In this reaction volume is increasing in the forward reaction. So on increasing temperature reaction will proceed in forward direction.
