Question

the overall change in enthalpy of a reaction depends only on
the reactants and the products.
the path that is taken from the reactants to the products.
the reactants and the catalysts only.
the reactants, the products, and the catalysts.

Explanation:

Enthalpy change (ΔH) is a state function, meaning it depends only on the initial (reactants) and final (products) states of a reaction, not the path taken or catalysts (catalysts speed up reactions but don’t change ΔH). So the correct option is the one stating it depends on reactants and products.

Answer:

the reactants and the products.
