← ScienceWhich consequence results when a catalyst doubles the rate constant?
A)Equilibrium shifts to product formation
B)Activation energy barrier decreases faster
C)Equilibrium constant remains unchanged✓
D)The reaction becomes thermodynamically favorable
💡 Explanation
The equilibrium constant remains unchanged because a catalyst alters the reaction rate by lowering the activation energy via an alternate pathway, therefore affecting forward and reverse rates equally, rather than shifting which ratio is favored by thermodynamics.
