Question

Describe the effect of:
(a) addition of $H_{2}$.
(b) addition of $CH_{3}OH$.
(c) removal of C.

Answer 1

The given reaction is as follows

$2{ H }_{ 2 }(g)\quad +\quad CO(g)\quad \leftrightarrow \quad { CH }_{ 3 }OH$

(a) According to the Lechatelier's principle, on addition of ${ H }_{ 2 }$, the “equilibrium” of the reaction given will “shift” in the “forward reaction”.

(b) On adding of $C{ H }_{ 3 }OH$, the “equilibrium” will change in the “backward direction”.

(c) On removing CO, the “equilibrium” will change in the “backward direction”.

(d) On removing $C{ H }_{ 3 }OH$, the “equilibrium” will change in the “forward direction”.

Answer 2

The given reaction is as follows

2{ H }_{ 2 }(g)\quad +\quad CO(g)\quad \leftrightarrow \quad { CH }_{ 3 }OH2H2​(g)+CO(g)↔CH3​OH

(a) According to the Lechatelier's principle, on addition of { H }_{ 2 }H2​ , the “equilibrium” of the reaction given will “shift” in the “forward reaction”.

(b) On adding of C{ H }_{ 3 }OHCH3​OH , the “equilibrium” will change in the “backward direction”.

(c) On removing CO, the “equilibrium” will change in the “backward direction”.

(d) On removing C{ H }_{ 3 }OHCH3​OH , the “equilibrium” will change in the “forward direction”.
