Chapter 10: Rate of Reaction

A. Knowledge (Definition, meaning and facts)	Check
What is rate of reaction? What is stated in the collision theory? What is activation energy? What is effective collision?
B. Understanding / Application / Analysis
Explain how surface area (size of reactant) can increase the rate of reaction based on collision theory. Explain how temperature can increase the rate of reaction based on collision theory. Explain how catalyst can increase the rate of reaction based on collision theory. Explain why hydrochloric acid of 2.0 moldm-3 is reacted faster with zinc compare to hydrochloric acid of 0.5 moldm-3 .
C. Synthesis
Hypothesis: The smaller the size of reactant, the higher the rate of reaction. Describe a laboratory experiment to confirm the hypothesis by using the reaction between calcium carbonate and hydrochloric acid. Describe a laboratory experiment to show that the presence of catalyst will increase the rate of decomposition of hydrogen peroxide. Describe a laboratory experiment to show that an increase in temperature will increase the rate of reaction between sodium thiosulphate solution and sulphuric acid.
