Episode 2 — Chemical Equilibrium

Energy of Chemical Change

Learners will be able to:

• Identify the characteristics of a chemical reaction, including changes in physical and chemical properties. • Explain the concept of activation energy and its role in initiating chemical reactions. • Calculate the heat of formation (ΔH) using the formula ΔH = energy of products - energy of reactants. • Interpret an energy profile graph to determine whether a reaction is exothermic or endothermic. • Describe the effect of catalysts on the activation energy and rate of a chemical reaction.
