#### Overview: Enthalpy and Entropy

This is an overview of Topic 25: Enthalpy and Entropy. It includes explanation of entropy, Gibbs free energy and typical calculation question.

#### Entropy 1

This video introduces the concept of entropy, how it changes with temperature and in chemical reactions.

#### Entropy 2

This video continues to explain entropy in terms of spontaneous equations and introduces gibbs free energy.

#### Calculating the Minimum Temperature a Reaction Takes Place Spontaneously

This video contains an example using gibbs free energy formula to calculate the minimum temperature where a reaction is feasible.

#### Awkward Gibbs Equation Question

Video explaining the link between the Gibbs equation to the equation of a straight line.
