Final answer:
Increasing the concentration of sodium chloride in the reaction AgNO₃(aq) + NaCl(aq) -> AgCl (s) + NaNO₃(aq) will cause the equilibrium conditions to shift to the right.
Step-by-step explanation:
According to Le Chatelier's principle, if the concentration of sodium chloride in the reaction AgNO₃(aq) + NaCl(aq) -> AgCl (s) + NaNO₃(aq) is increased, the equilibrium conditions will shift to the right.
This means that more products, AgCl and NaNO₃, will be formed and the concentration of the reactants, AgNO₃ and NaCl, will decrease. Increasing the concentration of sodium chloride causes the system to shift in the direction that opposes the increase in concentration.
