Which reaction is not effected by change in pressure

✓
${H_2} + {I_2}$ $\rightleftharpoons$ $2HI$
B
$2C + {O_2}$ $\rightleftharpoons$ $2CO$
C
${N_2} + 3{H_2}$ $\rightleftharpoons$ $2N{H_3}$
D
$PC{l_5}$ $\rightleftharpoons$ $PC{l_3} + C{l_2}$

✓

Answer

Correct option: A.

${H_2} + {I_2}$ $\rightleftharpoons$ $2HI$

(a) ${H_2} + {I_2}$ $\rightleftharpoons$ $2HI$ $⇒$ $\Delta n = 2 - 2 = 0$.
