Problem

Which of the following is true of an endothermic reaction?

a. Strong bonds break and weak bonds form: this means that more energy is released than absorbed. 

b. Weak bonds break and strong bonds form: this means that more energy is released than absorbed.

c. The bonds that break and those that form are of approximately the same strength.

d. Strong bonds break and weak bonds form: this means that more energy is absorbed than released.

e. Weak bonds break and strong bonds form: this means that more energy is absorbed than released.
