- Rate of reaction
- How it is affected? How it is increased?
- Temperature
- Increase in temperature
- Concentration/pressure
- Increase
- Catalyst
- Catalyst added
- Surface area
- Solid cut into smaller pieces
- Temperature
- Measuring
- Rate = amount of reactant / Time
- Percipitation
- When its no longer transparent
- Cross under liquid
- Change in mass
- Gas was released
- Quicker mass drop, quicker reaction
- Volume of Gas given off
- Through gas syringe
- Experiments
- Hydrochloric acid and marble chips
- Measured through gas volume
- Changing surface area
- Finer pieces act faster
- Magnesium and Hydrochloric acid
- Increasing concentration
- Measured with mass balance
- Higher acid concentration acts faster
- Sodium Thiosulfate and Hydrochloric acid
- Measured through the transparency
- Increasing surface area
- Higher temperature acts faster
- Breaking down of Hydrogen Peroxide
- Catalyst added
- Better catalysts give a better reaction
- Measured through gas syringe
- Hydrochloric acid and marble chips
- How it is affected? How it is increased?
