Syllabus Objectives – Speed of Reaction

Self Assessment Checklist

Speed of reaction I can do this!
(a) Describe the effect of concentration, pressure, particle size and temperature on the speeds of reactions and explain these effects in terms of collisions between reacting particles.  
(b) Define the term catalyst and describe the effect of catalysts (including enzymes) on the speeds of reactions.  
(c) Explain how pathways with lower activation energies account for the increase in speed of reaction.  
(d) State that some compounds act as catalysts in some industrial processes.  
(e) State that enzymes are biological catalysts.  
(f) Suggest a suitable method for investigating the effect of a particular variable on the speed of a reaction.
(g) Interpret experimental data obtained from experimental investigations on the speed of reaction.
