Energy and fuels
This unit is concerned with the study of the energy changes involved in chemical reactions. We can measure these changes and draw conclusions about the nature of particular reactions and relate them to the energy contained within individual bonds. We will find that some reactions gain energy while others lose energy and we will learn how to predict this difference and investigate our predictions in the laboratory. We will explore the concepts involved in the study of chemical kinetics or rates of reactions. These concepts of energetics and kinetics will be investigated within the context of fuels and an extended investigation will be carried out using a variety of hydrocarbons as fuel sources. Finally, we will consider the ecological impacts of using fossil fuels and some potential solutions for these problems.
Introductory Activity
As part of your initial thinking about this unit, consider the following and do some research about this topic. When you find something interesting or when you come across something that you would like to understand better, add this information to the discussion forum below. You don't need to address every question below, but you should contribute something to the discussion that will be interesting for the rest of the class to read. Don't forget, you must join this wiki before you can contribute.
1. What are some of the forms of energy that are used in societies?
2. What are some statistics around energy use, especially as it relates to transport?
3. How does an internal combustion engine work from a chemist's perspective?
4. What are some of the practical issues involved in the use of the internal combustion engine?
5. What is the energy density of a fuel and how is it measured?

- Run simulations 1, 2 and 3.
- Enter at least 5 different values into each simulation
- Plot the value for the maximum of each curve vs the variable you are changing (e.g. temperature)
- Draw conclusions about what the M-B Distribution curves are showing and what your graphs are showing.
