PAR 4.5 ENERGY, RATE OF A REACTION

What Energy sources did we use today? 

What types of energy did we use today?

What energy conversions did we do today? 

YOU WILL LEARN

- what chemical energy is, how to draw a reaction profile diagram and how to indicate activation energy and reaction energy in this diagram

- to show the energy effect of a catalyst in a reaction profile diagram

- to use the collision theory to explain the difference in the rat of a reaction..
