In the image above which represents the energy in the chemical bonds in a pile of firewood, mark these 5 points,
1. A pile of cold (low energy) ashes
2. A neatly stacked pile of wood
3. A roaring fire
4. Burning kindling begins to add energy to the pile
5. A pile of hot (but cooling) coals
Also What is activation energy? How does a catalyst affect activation energy? In one paragraph
Activation energy is the minimum amount of energy required to initiate a chemical reaction. It serves as a barrier that must be overcome for the reaction to occur. A catalyst is a substance that can lower the activation energy of a reaction, making it easier for the reaction to proceed. This is achieved by providing an alternative pathway for the reaction to take place, one that requires less energy to overcome. The catalyst itself is not consumed in the reaction and can be used repeatedly, making it a valuable tool in speeding up chemical reactions. By lowering the activation energy, a catalyst can increase the rate of a reaction without being changed or consumed in the process.
