Objectives
The overall objective of Introduction to Physical-Chemistry is to provide the fundamental scientific background and practical training in Chemistry that are the basis for the understanding of the world around us. A key general objective is the development of qualitative and quantitative problem-solving skills. Of comparable importance is to learn proper laboratory practices, execute experiments, interpret experimental results and draw reasonable conclusions. Specific learning objectives for this course include the development of conceptual understanding of: bulk properties and models of gases, liquids and solids; thermodynamic laws and their relation with equilibrium - entropy and free energy concepts; physical and chemical equilibria; acqueous equilibria; electrochemistry and chemical kinetics.
