Heat of Reaction

What students will learn

• By the end of the lesson, students should be able to:
• Define enthalpy change (ΔH) and distinguish clearly between exothermic and endothermic reactions with energy profile sketches.
• Define standard enthalpy of formation, standard enthalpy of combustion, and standard enthalpy of neutralization with relevant balanced thermochemical equations.
• Calculate the quantity of heat and molar enthalpy change from experimental calorimetry data using Q = mcΔθ.
• State Hess's law of constant heat summation.
