← ScienceWhich 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.
