• The initial rates method and half-life method

- (a) understand and use rate equations of the form rate = k [A]m[B]n (for which m and n are 0, 1 or 2)

- (b) deduce the order of a reaction from concentration–time graphs or from experimental data relating to

- (c) interpret experimental data in graphical form, including concentration–time and rate–concentration graphs

- (d) calculate an initial rate using concentration data

- (e) construct a rate equation
