← ScienceWhich outcome arises when a reversible catalytic reaction reaches equilibrium at high temperatures?
A)Increased catalyst surface area reduction
B)Equal forward and reverse reaction rates✓
C)Shifted equilibrium towards product formation
D)Decreased overall reaction enthalpy change
💡 Explanation
When a reversible reaction reaches equilibrium, the forward and reverse reactions proceed at equal rates because the change in Gibbs free energy is zero, leading to no net change in reactant or product concentrations. Therefore the forward and reverse rates are equal, rather than a shift in equilibrium or changes to the catalyst or enthalpy, requiring additional energy input.
