CHE 108LR – General Chemistry for Engineers II is a course that builds upon the concepts learned in Chemistry I and II, providing an in-depth understanding of chemical equilibrium, acid-base equilibria, thermodynamics, and electrochemistry. This article will explore the prerequisites, course content, laboratory experiments, career opportunities, and tips for success in CHE 108LR.
Prerequisites for CHE 108LR
To succeed in CHE 108LR, it is essential to have a solid foundation in Chemistry I and II, including a good understanding of atomic structure, chemical bonding, stoichiometry, and reactions. In addition, a strong background in mathematics is required, including algebra, trigonometry, and calculus.
Course Content
CHE 108LR covers several essential topics in General Chemistry that are critical for engineers, including chemical equilibrium, acid-base equilibria, thermodynamics, and electrochemistry.
Chemical Equilibrium
Chemical equilibrium refers to the state where the rates of the forward and reverse reactions are equal, resulting in no net change in the concentrations of reactants and products. This section covers the calculation of equilibrium constants and the application of Le Chatelier’s Principle to predict the direction of the reaction under different conditions.
Acid-Base Equilibria
Acid-base equilibria involve the transfer of protons between molecules, resulting in the formation of conjugate acid-base pairs. This section covers the definitions of acids and bases, the calculation of pH and pOH, and the application of acid-base equilibria to buffer solutions.
Thermodynamics
Thermodynamics deals with the relationships between energy, temperature, and entropy, and the direction and extent of chemical reactions. This section covers the calculation of enthalpy, entropy, and Gibbs free energy, and their application to predict the feasibility and spontaneity of chemical reactions.
Electrochemistry
Electrochemistry is the study of the relationship between electrical energy and chemical reactions, involving the transfer of electrons between species. This section covers the principles of electro chemical cells and the calculation of cell potentials using the Nernst equation.
Laboratory Experiments
CHE 108LR also includes laboratory experiments that provide hands-on experience in applying the concepts learned in lectures. The laboratory experiments include:
Experiment 1: Determination of a Chemical Equilibrium Constant
In this experiment, students will measure the equilibrium constant of a chemical reaction using spectrophotometry.
Experiment 2: Acid-Base Titrations
In this experiment, students will perform acid-base titrations to determine the concentration of an unknown acid or base.
Experiment 3: Thermodynamics of a Chemical Reaction
In this experiment, students will measure the enthalpy change of a chemical reaction using calorimetry.
Experiment 4: Electrochemical Cells
In this experiment, students will construct and measure the voltage of an electrochemical cell.
Career Opportunities for Engineers with General Chemistry Knowledge
Engineers with a strong background in General Chemistry are in high demand in many industries, including chemical, pharmaceutical, energy, and materials. They can work in research and development, product design, process optimization, quality control, and environmental protection. A solid foundation in General Chemistry also provides a good basis for further studies in other areas, such as chemical engineering, materials science, and nanotechnology.
