← ScienceWhich consequence results when the activation energy changes?
A)Reaction rate constant value changes✓
B)Reactant equilibrium concentration is eliminated
C)Enthalpy change of reaction diminishes
D)Equilibrium constant of reaction shifts
💡 Explanation
A change in activation energy alters the Arrhenius equation's exponential factor because it affects the reaction rate constant. Therefore, the reaction rate will change directly, rather than affecting equilibrium, enthalpy, or equilibrium constants, which relate differently to thermodynamics.
