Question

How does the equilibrium change with the removal of hydrogen (H2) gas from this equation? 2H2S ⇌ 2H2(g) + S2(g)

A. Equilibrium shifts right to produce more product.
B. Equilibrium shifts left to produce more reactant.
C. Equilibrium shifts right to produce less product.
D. Equilibrium shifts left to produce less reactant.

Answer 1

Equilibrium shifts left to produce more reactant

Answer 2

Answer : The correct option is, (A) Equilibrium shifts right to produce more product.

Explanation :

According to the Le Chatelier's principle, when we are adding or removing the products or reactants from the reaction, the equilibrium will shift towards that side where the less number of molecule.

The given equilibrium reaction is,

`2H_2S\rightleftharpoons 2H_2(g)+S_2(g)`

In the given reaction, when we are removing the hydrogen gas from the reaction then the equilibrium will shift towards the right side to produce more product.

Hence, the correct option is, (A)
