Catalysts don't affect the energy of what?

Catalysts don't affect the energy of what?

• A. Activation Energy
• B. Reactants and Products
• C. Temperature
• D. Entropy

Answer: (B)

The main idea is that catalysts change how fast a reaction happens, not the energies of the reactants and products themselves. A catalyst provides an alternative pathway with a lower activation energy, so more molecules can reach the transition state and react at a given temperature. But this new path doesn’t alter the actual energy content of the reactants or the products, nor the overall energy change of the reaction (or its entropy). It simply speeds up both the forward and reverse reactions, leaving the equilibrium position and the thermodynamic energies (the energy of the reactants and products) unchanged. So, catalysts don’t affect the energy of the reactants and products.
