Which outcome occurs when positive activation energy nears zero?

A)Reaction rate reaches equilibrium
B)Equilibrium constant nears unity
C)Rate constant approaches its maximum
D)Reverse reaction becomes very endothermic

💡 Explanation

A very low or zero activation energy allows the rate constant to approach to its maximum value, because the Arrhenius equation dictates an exponential relationship; therefore, the forward rate greatly increases, rather than equilibrating or affecting the reverse direction.
