#### Overview:

Reaction Rates

This is an overview of Topic 12: Reaction Rates. It includes factors that affect rate, initial rates, how to calculate rate from graphs and Boltzmann distribution curve.

#### Rates of reaction introduction

Video introducing rate of reaction including how to work out the rate from concentration/ time graph.

####
Rates of reaction collision theory

This video highlights how the collision theory is evidence for the effects of temperature, concentration, pressure, surface area and catalysts on the rates of reaction.

####
Rates of reaction – Boltzmann distribution curves

This video explains what Boltzmann distribution curves are, the information the curves provide and how the shape changes at different temperatures.

#### Colorimetry

This video explains the importance of colorimetry in the continuous monitoring of the rate of a reaction.
