Answer :
When you decrease the concentration of dihydrogen monosulfide (H2S) in a reaction, the equilibrium will shift to counteract this change. Here's what happens:
1. Decreasing the concentration of H2S means there are fewer H2S molecules available for the reaction.
2. According to Le Chatelier's Principle, when the concentration of a reactant decreases, the equilibrium shifts to the right to produce more of that reactant to counteract the change.
3. In this case, shifting the equilibrium to the right means that more H2S will be produced to make up for the decreased concentration.
4. As a result, the reaction will favor the forward reaction to produce more H2S until a new equilibrium is reached.
Therefore, if you decrease the concentration of H2S, the equilibrium will shift to the right to produce more H2S molecules.
