By now you should all have copies of the Study Guide and read the introductory notes. Class 1 Introduction Understanding and becoming familiar with chemistry is like understanding and becoming fluent in a language. Until limited by other factors, the rate of population growth is proportional to the number of people to have children.
Radioactive decay is a unimolecular process.
Examples of combinations of processes in reaction mechanisms giving nonlinear differential equations and other integrated expressions will be seen later. Nonlinear time differentials result from the combination of linear time differentials and give rise to other snapshot equations. There are sets of limiting or model conditions which define ideal chemical reactors. These model conditions may be approached in practice by real experimental reactors, although some real reactors are intermediate between the limiting models. Ideal reactors have characteristics which can be described mathematically in a far simple fashion than real, non-ideal reactors.
