Reaction Rates Template
Introduction (300 – 400 words):
P1
What is a chemical reaction? What is a clock reaction?
What was the purpose of investigation?
Brief description of what you did.
P2
Introduce chemical theory behind rate of reaction.
Temperature
Concentration
Surface Area
Catalyst (Discuss the use of an enzyme and their similarities)
P3
Relate this content to particle theory. (Activation energy etc)
Eg As the surface area decreases the particles will have more frequent collisions which will increase the chance of a faster rate of reaction.
P4
Variables
Independent variable: The one you changed.
Dependent variable: The one you measured.
Control variables: The ones you kept the same.
Hypothesis, Materials, Method, Results (table and graph), Risk assessment (100 word summary and attach risk assessment on moodle into appendices).
Analysis and Discussion: Explain why you go the results you did. Do not introduce any new theory!
P1
Do your results support your hypothesis?
Was your investigation a success?
P2
Explain your results.
P3
Discuss the limitations, errors in your investigation. Are they acceptable?
Some questions to consider??
Have you started by re-stating the hypothesis and either accepting or rejecting it?
Have you analysed your results? Were they what was expected? Discuss these with the reader in paragraph form.
Have you included your fully labeled graph?
Have you provided a paragraph analyzing and discussing your graph? Eg – was there a trend in the data – what does this mean - is this what was expected. Specifically reference the data points when discussing them (at temperature x, the time was y).
Which specific data points were less reliable or potentially incorrect? How have these data points affected your results?
Have you linked your results back to the theory and focus questions from the introduction? Remind the reader of the theory when discussing particular results, use it to help...
