Overview: How Fast?
This is an overview of Topic 21: “How Fast?”. It includes rate of reaction, order of reactants, overall order, rate determining step, rate constant and half-life.
Rate and Order of Reaction
This video introduces order of reaction and demonstrates how concentrate can affect rate thus resulting in different orders of reactions.
Order and Half-Life
This video explores the link between order of reaction and half-life and the information that half-life provides.
This video demonstrates how knowing the order of the reaction with respect to a particular reactant help form rate equations.
Initial Rates 1
This video looks at the initial rates method and includes 2 worked examples.
Initial Rates 2
This video continues to work through examples using the initial rates method.
Rate-Determining Steps and Reaction Mechanisms 1
This video introduces what the rate determining step is and provides worked examples of the reaction mechanism.
The Arrhenius Equation
This video explains how the rate constant and temperature are linked by the Arrhenius equation
Video with two worked examples using the Arrhenius equation.
This video demonstrates how to draw a graph to calculate Ea.
