Question
Use the reaction to answer the question.
Which describes this reaction, endothermic or exothermic? Why?
(1 point)
C2H6 + energy → C2H4 + H2
The reaction is endothermic, because more energy is released than taken in.
The reaction is endothermic, because more energy is taken in than released.
The reaction is exothermic, because more energy is released than taken in.
This reaction is exothermic, because more energy is taken in than released.

The correct answer is: **The reaction is endothermic, because more energy is taken in than released.**
In the equation given, energy is a reactant (on the left side of the equation), indicating that the reaction absorbs energy to proceed. This characteristic defines an endothermic reaction, as it requires an input of energy to break the bonds in the reactants (C2H6) to form the products (C2H4 and H2).
