Question

Which of the following correctly describes the net energy change during a reaction?

A. The net change in energy is positive for exothermic reactions where energy is required.
B. The net change in energy is positive for endothermic reactions where energy is required.
C. The net change in energy is negative for endothermic reactions where energy is required.
D. The net change in energy is positive for endothermic reactions where energy is released.

Answer 1

@dtan5457 C right?

Hmm, endothermic is when energy is absorbed, that means that the net change must be positive.

Endo=positive
exo=negative
