Two substances are in equilibrium in a reversible chemical reaction. If the concentration of each substance is doubled, then the value of the equilibrium constant will be___________________?
Correct answer: A. Same
- A. Same
- B. Doubled
- C. Halved
- D. One fourth of its original value
Explanation
The equilibrium constant depends on temperature, not on the instantaneous concentrations. Doubling concentrations disturbs the reaction quotient and may shift the equilibrium, but the final value of K at the same temperature is unchanged.
