For the following equilibrium reaction, predict the direction of the equilibrium shift by specifying if each stress will cause the concentration of reactants or products to increaseNH3(g)+H2O(l) ⇋ NH4+(aq)+OH−(aq)Drag the appropriate stresses to their respective bins.Adding NH4+(aq) Adding NH3(g) Adding OH-(aq) Removing NH4+(aq) Removing OH-(aq)Shifts in the direction of the reactants:Shift in the direction of the products:

Respuesta :

Answer:

Adding NH₄⁺(aq)- shift in the direction of the reactants.

Adding NH₃(g)- shift in the direction of the products.

Adding OH⁻(aq)- shift in the direction of the reactants.

Removing NH₄⁺(aq)- shift in the direction of the products.

Removing OH⁻(aq)- shift in the direction of the products.

Explanation:

According to the Le Chatelier's principle, any change in the reaction conditions of a given chemical reaction present at equilibrium, causes the equilibrium to shift in the direction that minimizes the effect of the change.

Given chemical reaction: NH₃(g) + H₂O(l) ⇋ NH₄⁺(aq) + OH⁻(aq)

Adding NH₄⁺(aq)- Addition of product, ammonium ion (NH₄⁺), causes the equilibrium to shift in the direction of the reactants.

Adding NH₃(g)- Addition of reactant, ammonia (NH₃), causes the equilibrium to shift in the direction of the products.

Adding OH⁻(aq)- Addition of product, hydroxide ion (OH⁻), causes the equilibrium to shift in the direction of the reactants.

Removing NH₄⁺(aq)- Removal of product, ammonium ion (NH₄⁺), causes the equilibrium to shift in the direction of the products.

Removing OH⁻(aq)- Removal of product, hydroxide ion (OH⁻), causes the equilibrium to shift in the direction of the products.

Adding NH₄⁺ (aq) ⇒ Shift in the direction of the reactants.

Adding NH₃ (g)⇒ Shift in the direction of the product.

Adding OH⁻ (aq) ⇒ Shift in the direction of the reactants.

Removing NH₄⁺ (aq) ⇒ Shift in the direction of the product.

Removing OH⁻ (aq) ⇒ Shift in the direction of the product.

Further explanation

In the equilibrium system, according to Le Chatelier, if there is a reaction there will be action

Reaction = - action

If the concentration of one component is enlarged, the system reaction is to reduce the component, and vice versa, if the concentration of one component is reduced, the reaction system is to add to the component

From reaction:

NH₃ (g) + H₂O (l) ⇋ NH₄⁺ (aq) + OH⁻ (aq)

  • Adding NH₄⁺  (aq)

The system will react by decreasing the concentration of products by moving to the left ---> Shifts in the direction of the reactants

  • Adding NH₃ (g)

The system will react by decreasing the concentration of reagents by moving to the right ----> Shift in the direction of the product:

  • Adding OH⁻ (aq)

The system will react by decreasing the concentration of products by moving to the left -> Shifts in the direction of the reactants

  • Removing NH₄⁺ (aq)

The system will react by increasing the concentration of products by moving to the right ----> Shift in the direction of the product:

  • Removing OH-⁻(aq)

The system will react by increasing the concentration of products by moving to the right ----> Shift in the direction of the product:
