Several important things affect how fast chemical reactions happen. Here are the main ones to understand:
Concentration: When there are more particles in a space, they bump into each other more often. This usually makes the reaction happen faster.
Temperature: If you heat things up, the particles move faster. This means they collide with each other more quickly and have more energy to start the reaction.
Surface Area: For solid materials, breaking them into smaller pieces (like chopping or grinding) makes more surfaces available to react. This leads to more collisions and speeds up the reaction.
Catalysts: These are special substances that help a reaction happen faster without getting used up in the process. They do this by lowering the energy needed to start the reaction.
Pressure: When dealing with gases, increasing the pressure pushes the particles closer together. This makes it more likely for them to collide and react.
By learning about these factors, we can better understand how quickly reactions will take place!
