- Catalysts
- Catalysts are substances that increase the rate of a chemical reaction.
- They are not used up in the process
- Manganese dioxide is an example of a catalyst
- Decomposes hydrogen peroxide to oxygen and water
- Catalysts are often used in the synthesis of organic chemicals by industry
- Catalyst are also important in preserving the environment
- With less energy required, less fossil fuel is burnt and less carbon dioxide released into the atmosphere.
- Adsorbtion:- The adhesion of a chemical species onto the surface of particles.
- Haber:- German chemist noted for the synthetic production of ammonia from the nitrogen in air
- Heterogeneous: A heterogeneous mixtures is one which has a non-uniform composition.
- Homogeneous: A substance can be defined as homogeneous if it contains only one kind of compound or one element.
- Enzyme:- A protein that acts as a catalyst in biological systems.
- Activation energy:- Amount of energy that must be absorbed by reactants in their ground states to reach the transition state so that a reaction can occur.
- Rate of reaction:- Change in the concentration of a reactant or product per unit time.
- Catalytic convertor:- A device in the exhaust system of a car that contains a catalyst that coverts pollutant gases into less harmful ones
- Biodegradable:- A substance or object Capable of being decomposed by bacteria or other living organisms.
