Responses

The reaction is endothermic, because more energy is taken in than released.
The reaction is endothermic, because more energy is taken in than released.

This reaction is exothermic, because more energy is taken in than released.
This reaction is exothermic, because more energy is taken in than released.

The reaction is exothermic, because more energy is released than taken in.
The reaction is exothermic, because more energy is released than taken in.

The reaction is endothermic, because more energy is released than taken in.

Answer 1

The correct response is:

The reaction is endothermic, because more energy is taken in than released.

This is because the reactant (C2H6) requires energy input to transform into the products (C2H4 and H2), indicating that energy is absorbed during the reaction.
