← ScienceWhich outcome occurs when a catalyst weakens bonds in reactants during chemical reaction?
A)Reaction equilibrium shifts noticeably towards products
B)Net endothermic nature of overall reaction decreases
C)Forward reaction rate rises more significantly✓
D)Reverse reaction rate decreases substantially
💡 Explanation
When a catalyst weakens reactant bonds, the activation energy required decreases, according to the Arrhenius equation, leading to an increased Boltzmann fraction molecules with sufficient energy. Therefore, the forward reaction rate rises more significantly, rather than a shift in equilibrium or change in overall endothermic nature influenced by thermodynamics.
