Presentation Transcript

  1. Aim: How to interpret potential energydiagrams? • A catalyst provides an alternate reaction pathway, which has a lower activation energy than an uncatalyzed reaction. • Chemical and physical changes can be exothermic or endothermic.

  2. Aim: How to interpret potential energydiagrams? • Energy released or absorbed during a chemical reaction can be represented by a potential energy diagram. • Energy released or absorbed during a chemical reaction (heat of reaction) is equal to the difference between the potential energy of the products and potential energy of the reactants.

  3. Aim: How to interpret potential energydiagrams? Essential Questions: • Use kinetic molecular theory (KMT) to explain rates of reactions and the relationships among temperature, pressure, and volume of a substance. • Explain heat in terms of kinetic molecular theory.
