← ScienceWhich outcome occurs when a reversible exothermic reaction reaches equilibrium?
A)Reaction rate remains constant (dynamic)✓
B)Forward reaction ceases entirely (static)
C)Reverse reaction rate accelerates rapidly
D)Internal energy increases instantaneously
💡 Explanation
Forward and reverse reactions continue equally during dynamic equilibrium, maintaining constant rates because reaction rates achieve balance, therefore rates do not stop or shift rather than either reaction dominates or an instantaneous change occurring.
