CHAPTER- 7 KINETICS - RATES OF REACTION SEMESTER1

 

                            

Fast and slow reactions

 

 

 

Some reactions are slower than others. For 

example:

• Rusting is a slow reaction
•  
• Burning and explosions are very fast reactions

Graphs

·         The rate of reaction can be analysed by plotting  graph of amount of product against time. The graph below shows this for two reactions.
