Which outcome occurs when a chemical reaction approaches equilibrium given fixed rate constants?

A)Forward and reverse rates converge
B)Activation energy barrier increases
C)Catalyst consumption rate accelerates
D)Reaction enthalpy change maximizes

💡 Explanation

When a reaction approaches equilibrium, the forward and reverse reaction rates become equal because the change in Gibbs free energy approaches zero, which directly relates to the rate constants. Therefore the forward and reverse rates converge, rather than changes in activation energy, catalyst consumption or enthalpy, which rely on different kinetic or thermodynamic parameters.
