← ScienceWhich outcome occurs when product concentration approaches equilibrium?
A)Reverse reaction rate accelerates notably✓
B)Catalyst action becomes exponentially faster
C)Activation energy barrier disappears entirely
D)Rate constants shift linearly upward
💡 Explanation
When products reach equilibrium, the reverse reaction rate accelerates, counteracting forward progress, because dynamic equilibrium demands balanced rates through the Le Chatelier's principle; therefore, the reverse rate increases rather than a change in catalysis which wouldn't affect inherent equilibrium.
