← ScienceWhich outcome occurs when thermal energy elevates reactants past the activation energy barrier?
A)Accelerated reaction rate increases sharply✓
B)Equilibrium shifts to favor reactants
C)Catalyst regeneration becomes rate-limiting
D)Enthalpy change approaches standard conditions
💡 Explanation
Elevated thermal energy causes more molecules to surpass the activation energy via Arrhenius equation, leading to *exponential increase* in reaction kinetics rates because this promotes more productive collisions; therefore the reaction accelerates sharply, rather than reversing equilibrium or limiting catalysis.
