Advanced Kinetics A Level Chemistry cambridge OCR and edexcel

A powerpoint document which covers Advanced Kinetics (Rate of reactions) chapters from the OCR A Level Chemistry, Cambridge chemistry and edexcel AL Specification.

tHIS DOCUMENT IS GOOD FOR LEARNERS AND TEACHERS teaching the above systems.
OBJECTIVES COVERED

1 explain and use the terms rate equation, order of reaction, overall order of reaction, rate constant, half-life,
rate-determining step and intermediate
2 (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
the initial rates method and half-life method
© 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
3 (a) show understanding that the half-life of a first-order reaction is independent of concentration
(b) use the half-life of a first-order reaction in calculations
4 calculate the numerical value of a rate constant, for example by:
(a) using the initial rates and the rate equation
(b) using the half-life, t1/2, and the equation k = 0.693/t1/2
5 for a multi-step reaction:
(a) suggest a reaction mechanism that is consistent with the rate equation and the equation for the overall
reaction
(b) predict the order that would result from a given reaction mechanism and rate-determining step
© deduce a rate equation using a given reaction mechanism and rate-determining step for a given reaction
(d) SN1 AND SN2 MECHANISMS
