प्रश्न
The addition of a catalyst during a chemical reaction alters which of the following quantities?
विकल्प
Enthalpy
Activation energy
Entropy
Internal energy

उत्तर
Activation energy
Explanation:
The addition of a catalyst provides an alternate reaction pathway with a lower activation energy, thereby increasing the reaction rate. It does not change entropy, internal energy, or enthalpy of the reaction. The catalyst lowers the activation energy barrier, but the overall energy change remains constant.
