← ScienceWhich outcome occurs when a sacrificial anode fails?
A)Unaffiliated metal experiences accelerated corrosion✓
B)Rate of electron flow decreases
C)Equilibrium shifts to reduce oxidation
D)Activation energy becomes artificially lowered
💡 Explanation
When a sacrificial anode is depleted, the reaction rates causing corrosion is accelerated as galvanic protection ceases, because the oxidation propagates uncontrolled as the process changes rather than electrons being donated selectively, therefore, oxidation accelerates.
