307. Tackling Enthalpy Calculations

Description

To succeed in this topic, you need to:
Be familiar with chemical change involving the transfer of energy between the chemical system and its surroundings.
Be familiar with measuring the enthalpy change, ΔH, in a chemical system and that energy is transformed from one form to another.
Be familiar with standard conditions and how standard enthalpy measurements are recorded at a constant pressure of 100 kPa, and at a temperature of 25oC (298 K).

After working through this Chemistry Factsheet, you will:
Be able to describe enthalpy as the thermodynamic property of a system, which cannot be measured directly.
Be able to describe Hess’s Law as the overall enthalpy change in a system being independent of the reaction pathway taken.
Be able to apply Hess’s cycles to determine the enthalpy change in relation to; enthalpy of reaction, enthalpies of formation, enthalpies of combustion, enthalpy of solution and bond enthalpies.
