The head TA of Introduction to Chemical Engineering (E20) fills in for Professor Channing Robertson and discusses how to construct a pharmacokinetics model using a virtual human "tank" model.
-
Professor Sylvia Ceyer investigates chemical reaction mechanisms: rate, order, molecularity, steady-state approximation, and rate determing steps.
-
The head TA for Introduction to Chemical Engineering (E20) fills in for Professor Channing Robinson and discusses a case study on the process of making high fructose corn syrup.
-
Professor Sylvia Ceyer explains the standard Gibbs free energy of formation and its relationship to thermodynamic stability. The Second Law of Thermodynamics is defined as it relates to controlling spontaneity with temperature. The lecture concludes by defining the thermodynamic equilibrium constant and the reaction quotient/direction of change in a chemical equilibrium.

Kim explains that the Two Towers development was done with a team of 40 at EA and the help of a third party developer in order to get it finished in time. The EA team injected their values, processes, management style and work ethic into the outside team, she says.

Professor Sylvia Ceyer covers radioactive decay and its various uses in modern medicine. Second order half-life, as a second order integrated rate law, is then discussed. The lecture concludes with the overlap of kinetics and chemical equilibrium: the equilibrium constant, elementary reactions, and an example, the decomposition of ozone.

Review. Professor Sylvia Ceyer reviews the main topics covered throughout the second half of the course including kinetics, transition metals, VSEPR theory, acid-base equilibrium, chemical equilibrium, and oxidation/reduction. Professor Ceyer uses the case study of methionine synthase to supplement the discussion.

The Big Bang created the physical universe. Of course life is part of this physical universe, but the immediate building blocks of life are chemicals. Before the Big Bang, words such as “time” had no meaning, but even in the first few minutes there could be no chemistry since there were no atoms. The nuclei of some of the lighter elements formed within minutes, atoms some time later, and elements heavier than lithium were forged in the sup...more

August 21, 2008 presentation by Stacey Bent for the Stanford University Office of Science Outreach's Summer Science Lecture Series. Meeting the world's growing energy needs in a sustainable fashion is one of the most pressing problems of our time. Professor Bent introduces the scope of the energy problem and some of the options for sustainable energy, then will focus on two main devices: solar cells and fuel cells. Solar cells convert t...more
