To determine whether a shift will occur in the direction of the reactants or the products, you need to analyze the effect of the changes mentioned in the question on the equilibrium position. Here's how you can approach each change:
1. Removing some HC2H302 (aq):
If you remove some HC2H302 (aq) from the reaction mixture, you are effectively reducing the concentration of this reactant. According to Le Chatelier's principle, the system will compensate for the loss by shifting the equilibrium in the direction that replenishes the reactant. Therefore, the shift will occur in the direction of the reactants.
2. Removing some С2Н302- (aq):
Removing some С2Н302- (aq) from the mixture reduces the concentration of this product. To restore the equilibrium, the system will shift in the direction that produces more С2Н302- (aq). Hence, the shift will occur in the direction of the products.
3. Adding more НС2Нз02 (aq):
By adding more HC2H302 (aq) to the reaction mixture, you increase its concentration. To compensate for the addition, the equilibrium will shift in the direction that consumes HC2H302 (aq). Thus, the shift will occur in the direction of the products.
4. Adding more C2H302- (aq):
Adding more C2H302- (aq) increases its concentration in the mixture. In response, the equilibrium will shift in the direction that reduces the excess C2H302- (aq). Thus, the shift will occur in the direction of the reactants.
In summary:
- Removing HC2H302 (aq) shifts in the direction of the reactants.
- Removing С2Н302- (aq) shifts in the direction of the products.
- Adding HC2H302 (aq) shifts in the direction of the products.
- Adding C2H302- (aq) shifts in the direction of the reactants.
