Chemical reactions
- Signs
- Gas given off
- Change in colour
- Solid formed
- Light given off
- Product is created
- Fizz or bubbles
- Factors effecting reaction rate
- Temperature
- The higher the temperature ......
- More kinetic energy provided
- More collisions
- The faster the reaction
- Particle size
- As the particle size decreases...
- Surface area gets bigger
- Faster reaction
- Concentration
- As the concentration increases..
- The rate of reaction increases also
- Using a Catalyst
- Speeds up chemical reaction
- Remains unchanged
- Reusable
- Measuring rate
- Divide the initial mass /vol By the time
