Physical Chemistry #24: Reaction Kinetics a the Effects of Concentration (Slides and Tasks)

In this lesson we introduce the concept of reaction kinetics focusing on collision theory, rates of reaction, activation energy and the effect that changing concentration and pressure will have on reaction rates. This is lesson twenty four in our physical chemistry series for Unit 8: Reaction kinetics (from the Cambridge International AS Chemistry Curriculum (9701) 2019-2021 curriculum).

LESSON OBJECTIVE: Define rate of reactions in terms of collision theory and activation energy and understand the effect concentration has on reaction rates.

LEARNING OUTCOMES (taken from the Cambridge International AS and A Level Chemistry (9701) 2019-2021 curriculum):
8.1 Simple Rate Equations, Orders of Reaction and Rate Constants
a) explain and use the term rate of reaction

b) explain qualitatively, in terms of collisions, the effect of concentration changes on the rate of reaction
