Effect of Catalysts

• Catalysts= substances that speed up a chemical reaction/lowers temperature by lowering activation energy
• The graph shows the effect of catalysts to activation energy

  
• Everyday catalysts:

  • Nickel
  • Iron
  • Platinum
• Catalysts do not get used up in reactions and can be reused , which is why they aren't shown in equations
• Using catalysts in the industry can:

  • Lower prices on energy needed to melt/react materials
  • Increase rate of reaction (Less time)
