Chemical Thermodynamics

• Enthalpy - denoted by 'h' refers to the measure of total heat content in a thermodynamic system under constant pressure
• Entropy - denoted by 's' refers to the measure of the level of disorder in a thermodynamic system
• Enthalpy - Jmol$^-1$
• Entropy - JK$^-1$
• Second Law of Thermodynamics - "The total entropy of the universe is continuously increasing"
• Josiah Willard Gibbs introduced the Gibbs Free Energy
• If G is negative - reaction is product favored
• If G is positive - reaction is reactant favored
