Answer:
The equilibrium will shift to the right
Explanation:
The chemical equilibrium represents a balance between direct and inverse reactions.
The Le Chatelier Principle states that variations in experimental conditions can alter this balance and displace the equilibrium position, causing more or less of the desired product to form. And in this way the system evolves in the opposite direction so as to counteract the effects of such disturbance.
The variation of one or more of the following factors are those that can alter the equilibrium condition:
- Temperature
- The pressure
- The volume
- The concentration of reactants or products
In this case:
NaOH produces OH⁻ ions. OH⁻ ion uses up H₃O⁺ through the reaction:
H₃O⁺ + OH⁻ → 2 H₂O
According to the Le Chatelier principle, the addition of NaOH consumes one of the products, decreasing its concentration. Therefore, to balance the reaction, the equilibrium will shift to the right in order to counteract the effect that disturbed it and recover the equilibrium state.
The addition of NaOH, results in the concentration of the products to be decreased and the reaction has been forwarded in the right direction.
The equilibrium equation of the nitrous acid results in the formation of hydronium ions and nitrite ions. The direction of the reaction has been decided with the concentration of the products and the reactant.
At the equilibrium, the concentration of products and reactants are equal. If the concentration of reactants has been decreased, the reaction shifts towards the left direction. If the concentration of products has been decreased, the reaction will shift towards the right direction.
The addition of NaOH results in the consumption of the hydronium ion product. Hence, the concentration of the products has been decreased and the reaction has been forwarded in the right direction.
