← ScienceWhich outcome results when a catalyst with strong product affinity is introduced to a reversible reaction at equilibrium?
A)Increased reverse reaction rate
B)A shift in equilibrium towards reactants✓
C)Reduced activation energy for reverse reaction
D)No net change in equilibrium concentrations
💡 Explanation
The strong product affinity of the catalyst lowers the effective concentration of product available for the reverse reaction because Le Chatelier's principle dictates the equilibrium will shift away from changes. Therefore equilibrium shifts towards reactants, rather than increased reverse rate or maintaining equilibrium, which require different catalyst actions.
