Which of the following thermodynamic or kinetic properties is NOT altered by the addition of a posit — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

A catalyst actively creates a new reaction pathway, lowering both $E_{a(f)}$ and $E_{a(b)}$ by the exact same magnitude, which increases both rate constants. However, because it lowers both sides equally, the net energy difference ($\Delta H$) and equilibrium constant remain absolutely unchanged.
