Question

For a reversible system at a constant temperature, the value of $K_c$ increases if the concentrations are changed at equilibrium.

• A. True
• B. False

Answer 1

The correct option is A True

For a reversible system at a constant temperature, the value of $K_c$ remains same if the concentrations are changed at equilibrium. When more reactants are added, the equilibrium will shift in the forward direction to form more products. But the value of the equilibrium constant will remain same. Similarly, when more products are added, the equilibrium will shift in the reverse direction to form more reactants and the value of the equilibrium constant will remain same.
