Which change results when a fuel cell reaches equilibrium?

A)Reactions proceed in both directions equally
B)Electrolyte concentration sees a rapid increase
C)Increased electrode fouling accelerates corrosion
D)Enhanced product output surpasses input rate

💡 Explanation

At equilibrium, the forward and reverse reaction rates become equal because the Gibbs free energy is minimized by balancing reactant and product concentrations; therefore, the reaction doesn't favor product formation, rather than favoring reactants during the initial phase.
