First question please short answer: A pile of firewood is more stable as ash and smoke than firewood. Why does this pile of firewood not immediately release the energy in Its chemical bonds? (use the word activation energy in your answer)
Second question:
A strong bond is a (stable / unstable) bond.
2(H—C≡C—H) + 5(O=O) → 4(O=C=O) + 2(H—O—H)
First question: The pile of firewood does not immediately release the energy in its chemical bonds because it requires an input of activation energy to initiate the combustion reaction.
Second question: A strong bond is a stable bond.
