Fundamentals of Thermodynamics and Equilibrium

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• Calculate the pH for different solution mixtures involving strong and weak acids and bases.
• Explain basic principles including perfect gas behaviour, fundamental forces in chemistry, state functions, spontaneity of reactions, phase diagrams and titration curves.
• Describe the thermodynamics of phase transitions, and of ideal gas and liquid mixtures, and how dilution affects melting and boiling points in mixtures.
• Calculate the equilibrium constants, standard Gibbs energy of reactions, and standard cell potentials for Galvanic cells.
• Apply the concept of thermodynamic equilibrium.
• Define the terms and determine the enthalpy, entropy and Gibbs energy change associated with a reaction.

Subject Specific Practical Skills

Having successfully completed this module you will be able to:

• Meet the learning outcomes of a co-requisite practical module.
