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