Objectives

Section 1: Energy Transfer

    1. Define enthalpy.

    2. Distinguish between heat and temperature.

    3. Perform calculations using molar heat capacity.

Section 2: Using Enthalpy

    1. Define thermodynamics.

    2. Calculate the enthalpy change for a given amount of substance for a given change in temperature.

Section 3: Changes in Enthalpy

    1. Explain the principles of Calorimetry.

    2. Use Hess's law and standard enthalpies of formation to calculate ΔH.

Section 4: Order and Spontaneity

    1. Define entropy, and describe the factors that influence the sign and magnitude of ΔS for a chemical reaction.

    2. Describe Gibbs energy, and describe the factors that influence the sign and magnitude of ΔG.

    3. Indicate whether ΔG values describe spontaneous or non-spontaneous reactions.

Spiritual Concept

    1. Define enthalpy, entropy and Gibbs Free Energy.

    2. Write a paragraph that either a) relates these three concepts to the Trinity, or b) relates these three concepts to death, sin and life, or b) relate these three concepts to some other spiritual concept of your choosing.
