← ScienceWhich equilibrium shift happens once excess product builds within reversible reactions?
A)The rate of reverse reaction accelerates✓
B)The forward reaction rate remains constant
C)The activation energy threshold decreases
D)Kinetic isotope effects become negligible
💡 Explanation
Increased product decreases the concentration driving the forward reaction; therefore, the equilibrium adjusts toward the reverse, thus accelerating the rate to restore equilibrium, because Le Chatelier's principle guides the direction rather than any intrinsic property modulation.
