The lessons... |
Explosions are very fast reactions, while rusting and other reactions are slow. You learnt about the factors which affect the rate of reactions, including temperature, concentration, pressure and surface area. You also looked at the role of catalysts and why they are useful in industrial chemical processes.
You looked at some of the calculations that are used by chemical engineers to develop processes that are as economic and 'green' as possible. These calculations included: percentage yield; atom economy, energy transferred and relative formula mass. You also investigated why different reactions behave in alternative ways - Some give out energy while others take energy in. The development of pharmaceutical drugs is big business and in this topic you looked at how they are developed, tested, manufactured and marketed. Finally, you learnt about the different forms of carbon and their uses. |
