Rate of reaction

1. The effect of catalysts

1.1. A catalysts is substance that is added to the reactants to increase the rate

2. Factors effecting rates of reaction

2.1. •concentration

2.2. •Particle saiz

2.3. •Temperature

2.4. •catalyst

3. Measuring

3.1. Rate is measure of the change amount of time

3.2. Produce in certain amount of time

4. Biogical catalysts

4.1. Enzymes

4.2. Life process in plant and animal

4.3. Made from proteins

4.4. Destroyed by heat

5. The effect of temperature

5.1. If the temperature raised the rate of reaction increase

5.2. If temperature lowered the rate of reaction decreases
