  • 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.
  • 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.
  • Heterogeneous:  A heterogeneous mixtures is one which has a non-uniform composition.

This is one of the worst mindmaps I have ever seen.. My pet turtle could do a better job and he passed away 5 years ago!
