In a reversible chemical reaction having two reactants in equilibrium, if the concentration of the reactants are doubled, then the equilibrium constant will________________?
Correct answer: A. Remain the same
- A. Remain the same
- B. Be halved
- C. Also be doubled
- D. Become one fourth
Explanation
At a fixed temperature, the equilibrium constant depends only on temperature and the reaction stoichiometry, not on the starting concentrations. Doubling the reactant concentrations changes the equilibrium position, but not K.
