Rate expressions tied to stoichiometry, the units of k, order against molecularity, the zero- and first-order integrated laws, Arrhenius and activation energy, and three kinds of catalysis.
Unit 1 carries 17 of the 50 chemistry marks; with fourteen chapters sharing them, this one averages a little over one (MEC publishes weights by unit, not by chapter). Kinetics is the chapter that pays best per hour of study, because almost all of it reduces to four formulae and one graph, and because the first-order half-life reappears untouched in Nuclear chemistry two chapters later.
The MEC scope line runs: Rate of reaction and equivalent rate expressions; rate constant and its unit, order and molecularity; integrated rate laws for zero- and first-order reactions, their half-lives and characteristics; collision theory, activation energy, threshold energy and the activated complex; factors affecting rate; homogeneous, heterogeneous and enzyme catalysis; related numerical problems. The headings below are its points, in MEC's order.
