← ScienceWhich outcome occurs the instantaneous reactant concentration exceeds needed activation energy?
A)Increased exothermic reaction rate constant✓
B)Decreased endothermic reaction yield
C)Equilibrium shifts towards reverse reaction
D)Catalyst experiences permanent saturation
💡 Explanation
An increased reaction rate happens because the Arrhenius equation shows that higher activation energy leads to an exponential increase in the rate constant via Boltzmann distribution. Therefore, the reaction rate increases, rather than decreasing the reactant yield or the equilibrium shifting.
