1 Thermodynamics

2 Heat Curve

3 Types of Reactions Exothermic - Energy is released
Surroundings get hot Endothermic - Energy is absorbed Surrroundings get cold

4 Exothermic Diagram Ea Activation Energy - ∆H Energy Reaction Progress
Reactant - ∆H Energy Product Reaction Progress

5 Kinetics Rates of reactions Increase rate by More surface area
Higher temperature Higher concentration Catalyst

6 Catalyzed Reaction Ea is lowered - ∆H Energy Reaction Progress
Reactant Ea is lowered - ∆H Energy Product Reaction Progress

7 Calculating Heat Heat = C x m x ∆T Temp Change = T2-T1 Mass (g)
Specific Heat = energy needed to raise 1 g of Substance 1°C

8 Calculating Heat A 25.0 g piece of metal that absorbs 500 J of energy as it goes from 25°C to 35°C. What is the specific heat?
