Question

according to le chatelier’s principle, what happens to the equilibrium constant (k) when the concentration of the reactants is doubled?
○ the value of the equilibrium constant (k) is doubled.
○ the value of the equilibrium constant (k) is halved.
○ the value of the equilibrium constant (k) remains the same.
○ the value of the equilibrium constant (k) changes unpredictably.

Explanation:

Le Chatelier's principle states that the equilibrium constant \( K \) depends only on temperature. Changing the concentration of reactants (or products) will cause the system to shift to re - establish equilibrium, but it does not change the value of \( K \). When the concentration of reactants is doubled, the system will shift in the forward or reverse direction to reach equilibrium again, but the ratio of the concentrations of products to reactants (raised to their respective stoichiometric coefficients) at equilibrium (which is \( K \)) will remain unchanged.

Answer:

The value of the equilibrium constant (K) remains the same.
