For a reversible reaction, if we increase concentration of the reactants, then effect on equilibrium constant

Options

(a) depends on amount of concentration
(b) remains unchanged
(c) decreases
(d) increases

Correct Answer:

remains unchanged

Explanation:

For a reaction, A + B ⇌ C + D.

K(eq) = [C][D]/[A][B].

Increase in conc.of reactants will proceed the equilibrium in the forward direction giving more products. So that the equilibrium constant value remains constant and independent of concentration.
