Suppose in a dying star, a reaction takes place under extreme pressure and temperature. This reaction is hypothetically as follows:


a. Endoergic
b. Exoergic


c. Elastic
d. Break-even
e. Fission



a.
The reaction is endoergic because of the mass energies associated with the products and reactants. The reaction takes in energy on the entrance channel of the equation to produce the exit channel. This reaction shows that after iron, the binding energy per nucleon decreases, meaning that any reaction fusing an element more massive than iron will perform an endoergic reaction.
