中文简介:
在化学131C中，学生将学习如何计算系统的宏观化学性质。本课程将建立在微观理解（化学物理）的基础上，以加强和扩展您对普通化学（物理化学）中的基本热化学概念的理解。然后，我们将继续研究如何根据分子性质测量和计算化学反应速率。主题包括：能量、熵和热力学势；化学平衡；和化学动力学。热力学和化学动力学（Chem 131C）是OpenChem的一部分。这段视频是Reginald M教授在加州大学欧文分校讲授的题为&Quot；热力学和化学动力学&Quot；的27讲本科课程的一部分。.Penner.记录于2012年4月18日。00:01-公告00:58-示例：三原子分子，二氧化氯…04:27-方程（图）图09:40-热力学11:39-能量14:24-在热力学中，我们将宇宙划分为系统…15:30-图：现在有三种类型的系统：17:32-热力学震击术语表关于（平衡的类型）18:15-我们将讨论封闭系统，直到进一步的注意。20:23-现在，我们知道什么是热，但是什么是功？21:28——让我们来考虑机械功……23:54——外力是：25:57——现在体积会怎么样？28:27-示例：计算压缩所需的功…30:15-我们的工作方程…31:45-回答：以图形方式，本实验如下所示…34:23-因此，不使用所需的整个质量压缩活塞…35:01-图：步骤135:18-步骤236:22-结论：36:24-图：因此，更多步骤意味着更少的功。36:52-in热力学，一个可逆过程，是任何一个过程，它的方向可以被……38:54-图：代替把质量分成两部分……40:07-…一次加一个颗粒到活塞40:50-作为一个例子……43:38-图：总结：44:37-让我指出这两个方程都符合……45:47-其他工作的味道……46:27-那是W，Q呢？所需属性：Penner，Reginald热力学和化学动力学131C（UCI开放式课件：加州大学欧文分校）
课程简介: 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.Thermodynamics and Chemical Dynamics (Chem 131C) is part of OpenChem.This video is part of a 27-lecture undergraduate-level course titled "Thermodynamics and Chemical Dynamics" taught at UC Irvine by Professor Reginald M. Penner.Recorded on April 18, 2012.00:01 - Announcements00:58 - Example: the triatomic molecule, chlorine dioxide...04:27 - Plot of equation (Diagram)09:40 - Thermodynamics11:39 - Energy14:24 - In Thermodynamics, we divide the universe into the system...15:30 - Diagram: Now there are three flavors of systems:17:32 - Glossary of Thermodynamic Jargon (Types of Equilibrium)18:15 - We'll be talking about closed systems until further notice.20:23 - now, we know what heat is, but what is work?21:28 - let's think about mechanical work...23:54 - the external force is:25:57 - now what happens to the volume?28:27 - Example: Calculate the work required to compress...30:15 - Our equation for work...31:45 - Answer: Graphically, this experiment is as shown below...34:23 - So instead of compressing the piston using the entire mass necessary...35:01 - Diagram: Step 135:18 - Step 236:22 - Conclusion:36:24 - Diagram: so, more steps means less work.36:52 - In the thermodynamics, a reversible process is any process the direction of which can be reversed by...38:54 - Diagram: so instead of dividing the mass into two parts...40:07 - ...add one granule at a time to the piston40:50 - So as an example...43:38 - Chart: Summary:44:37 - Let me just point out that both of these equations conform...45:47 - other flavors of work...46:27 - that's w, what about q?Required attribution: Penner, Reginald Thermodynamics and Chemical Dynamics 131C (UCI OpenCourseWare: University of California, Irvine)
