#### 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.

#### Rate Equations

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

#### Arrhenius Calculations

Video with two worked examples using the Arrhenius equation.

#### Arrhenius Plots

This video demonstrates how to draw a graph to calculate Ea.
