The equilibrium constant of a catalytic chemical reaction _______________ due to the presence of?
Correct answer: D. Remain unaffected
- A. a catalyst.
- B. Increases
- C. Decreases
- D. Remain unaffected
- E. Unpredictable from the data
Explanation
A catalyst changes the rates of forward and reverse reactions without changing their thermodynamic balance. Therefore, the equilibrium constant remains unaffected by the catalyst.
