← ScienceWhich outcome results when the **equilibrium constant** varies with fixed conditions other than temperature in a reactive chemical system?
A)The reaction shifts equilibrium position.✓
B)Catalysis decreases apparent activation energy.
C)Reaction rates remain largely unaffected.
D)Activation energy increases exponentially.
💡 Explanation
The equilibrium shifts, caused by **Le Chatelier's principle**, because a change in variables (other than temperature that changes the constant), will alter the balance. Therefore, the equilibrium position is shifted, rather than the activation energy changing without a catalyst or the rates staying constant.
