Question

Use LeCha^telier?s principle to predict if each the following changes causes the system to shift in the direction of products or reactants:

HS?(aq)+H2O(l)?H3O+(aq)+S2?(aq)

A. removing some S2?(aq)

B. adding some HS?(aq)

C. removing some HS?(aq)

D. adding some H3O+(aq)

Answer 1

1)

Removing product will shift the reaction in the direction of product as per Le chatelier Principle

So, Equilibrium moves to product side

2)

Adding reactant will shift the reaction in the direction of product as per Le chatelier Principle

So, Equilibrium moves to product side

3)

Removing reactant will shift the reaction in the direction of reactant as per Le chatelier Principle

So, Equilibrium moves to reactant side

4)

Adding product will shift the reaction in the direction of reactant as per Le chatelier Principle

So, Equilibrium moves to reactant side
