O Level Chemistry: Energy Changes (Exo/Endo) & Bond Energy

Yesterday, we have gone through the theory of Energy Changes as well as look into one of the question of Endothermic/Exothermic reaction.

Let’s try one Multiple Choice Question (MCQ) to see if you understand it.

Quick Check 1:

PS: I strongly suggest you to leave your answers in the Comment Section right below this blog. Many of you will be waiting for answers directly from me. But in this way, your learning will not be effective. As such, i am looking forward to you trying out and leaving us an aswer.

    Hi Amanda,

    You are spot on! This question test students on their ability to identify reactions that involves Bond-Breaking.

    Bond-breaking processes are indeed Endothermic.

    Keep up the good work!
