How do chemical reactions occur?

 ⚗️ How Do Chemical Reactions Occur?

• A chemical reaction happens when substances (reactants) interact and their atoms rearrange to form new substances (products).

🔑 Key Points:

• Bonds break in the reactants.
• Atoms rearrange.
• New bonds form to create products.
• Energy is either absorbed or released.
• New bonds form to make water molecules.

What triggers a reaction?

• Collision of particles with enough energy.
• Sometimes a catalyst helps speed it up.
• Conditions like temperature, pressure, and concentration matter.
