Slide Information 00:05 - some announcements... 02:37 - today... 03:36 - Svante Arrhenius 04:20 - Arrhenius discovered the greenhouse effect in 1896 04:39 - Article Arrhenius wrote about climate change 05:59 - experimentally we often observe an acceleration...Arrhenius Equation. 10:25 - consecutive reactions are sequences of reactions... 11:49 - an understanding of consecutive reactions is important... 12:44 - consider this generic consecutive reaction: 14:28 - what do these equations predict about [B] versus time? 18:02 - Ok, now let's look at the other possibility: 18:36 - what if... 20:23 - this suggests an expedient method for dealing with...steady-state approximation 25:50 - So - how does this compare with the exact solution? 27:08 - ...Let's first examine a case where we expect that it will work well... 28:40 - now we'll make... 29:16 - now a case where we expect... 30:32 - ...and this is a complete disaster - just as expected. 31:16 - the Steady-State Approximation: 33:43 - REMEMBER: this works if... 33:58 - Irvine Langmuir 35:00 - a page from G.N. Lewis's lab notebook... 35:26 - Photo: How does this work (tungsten bulb)? 37:35 - until 1906, all lightbulbs had carbon filaments. These bulbs were also evacuated 42:20 - the Lindeman-Hinshelwood mechanism... 48:18 - let's apply the steady-state approximation...
In Chemistry 131C, students will study how to calculate macroscopic chemical properties of systems. This course will build on the microscopic understanding (Chemical Physics) to reinforce and expand your understanding of the basic thermo-chemistry concepts from General Chemistry (Physical Chemistry.) We then go on to study how chemical reaction rates are measured and calculated from molecular properties. Topics covered include: Energy, entropy, and the thermodynamic potentials; Chemical equilibrium; and Chemical kinetics.
