Statement 1: Reaction enthalpy remains unchanged in the presence of a catalyst.
Statement 2: A catalyst can form a different activated complex and lower activation energy, but the energy difference between reactants and products stays the same.
Options:
Answer:
A
Solution:
The explanation directly supports the unchanged reaction enthalpy: a different pathway does not alter the endpoint energy difference.
