1. Introduction and briefing
Starter…
H/W…
Write a summary of the literature and consider how YOU might investigate rates of reactions. How will you do it? Use the briefing notes for help.
Due next week’s 1st single lesson
What factors affect the rate of reaction?
How can we measure the rate of a reaction?
Review question maybe using a mind map on a white board

2. Answers? What factors affect the rate of reaction?
How can we measure the rate of a reaction?

3. 5 week plan planning lessons
Week 1 – Briefing
Week 2 – Planning
Week 3 – Planning
Week 4 – Trials for CPAC
Week 5 – Rates CPAC
If you miss a session you MUST download the PowerPoint from the shared area and collect associated materials, this is your responsibility.
You must complete all homeworks or you will not be allowed onto Y13 chemistry. No excuses

4. A2 chemistry topics Rates of reaction Entropy Equilibria
Further organic chemistry
Spectroscopy and chromatography
Redox chemistry / electrochemistry

8. The investigation
Plan and carry out an investigation to determine the rate equation for the reaction between Mg and HCl. How?
Find and read the research papers
Make notes on factors that you could investigate, what you will change, how you will carry out your experiment
Plan your experiment
Carry out trial experiments
Collect your results
Produce a graph and results tables
Write up the project

9. The investigation
Plan and carry out an investigation to determine the rate equation for the reaction between
magnesium and hydrochloric acid
Word equation?
Symbol equation inc state symbols?
Balanced?
How might we investigate this? What are the potential variables?

10. The investigation – Thoughts?
HCl
Volume?
Concentration? Mg
Mass?
Size and shape?
Flat or curled?
Oxide layer that forms?
When Mg had fully reacted, reaction has finished? H2
Volume collected?
When H2 reaches 100cm3 reaction finished?
Overall
Exothermic reaction, how will this affect the rate?
What combinations do we need?
Mg(s) HCl(aq)  MgCl2(aq) H2(g)
This is a lot to consider when planning an experiment from scratch. We will give you some suggestions on quantities but perhaps someone has already considered some of this? Ultimately this is YOUR experiment.

11. Initial reading

12. How to write a summary
Read the abstract to get an idea of the premise behind the paper.
Skip to the conclusion to get an idea of where the proposed research ends up.
Scan the article to get an idea of the main points of discussion.
Take ROUGH notes of KEY points as you read .
Decide what aspects if the article are most important to you (in the context of your experiment).
Condense the article into 4 main section…
Defining the research question
Summarising the methodology
Summarising the results
Relating this to your study
1 page of A4 should be more than sufficient.
