In this lesson we discuss how to calculate enthalpy changes using the equation ΔH=–mcΔT, specific heat capacity and the concept of calorimetry as an experimental technique. This is lesson sixteen in our physical chemistry series for Unit 5: Chemical Energetics (from the Cambridge International AS Chemistry Curriculum (9701) 2019-2021 curriculum).
LESSON OBJECTIVE: Understand how to calculate the enthalpy change of a reaction from experimental data obtained via calorimetry.
LEARNING OUTCOMES (from the Cambridge International AS and A Level Chemistry (9701) 2019-2021 curriculum):
5.1 Enthalpy change, ΔH
c) calculate enthalpy changes from appropriate experimental results, including the use of the relationship ΔH = –mcΔT
