## Suggestions for the Physical Chemistry Course

,

Abstract

In order to improve the teaching performance in the course of physical chemistry, the following four suggestions were given in this paper:(1) advances in the physical chemistry research field should be incorporated in the course; (2) the course should be arranged in the way beneficial to increasing the ability of students for solving the practical scientific problems; (3) the connection between knowledges should be clearly summarized in the course; (4) what and how problems can be solved using the knowledges should be clearly known by the students after the course.

Keywords： Advancement of science ; Framework of the content ; Connection between knowledges ; Scientific application

### 1.2 有大表面固体材料参与的化学反应热力学

${{G}_{\text{m},大表面}}-{{G}_{\text{m},常规}}=\sigma {{A}_{\text{s,m}}}$

ΔGm (MgO, s) = σAs,m = 1.2 × 40.3 × 200 J∙mol-1 = 9.7 kJ∙mol-1

ΔGm (W, s) = σAs,m = 2.9 × 183.85 × 200 J∙mol-1 = 106.6 kJ∙mol-1

### 2.1 简单的水利问题

A1.让水从一个指定位置“流”到另一个指定位置，是否需要电功？

A2.在哪里建水电站，流动1 m3的水，才可获得更大的电能？最多可获得多少电能？

A3.让水从一个低处的指定位置“流”到某高处的指定位置，实现该过程至少需要多少电能？至少需要的电能为流过水的势能。

### 2.2 物理化学问题

B1.怎样判断一个过程(例如化学过程)是否自发发生？

B2.利用什么样的过程才可获得更多的电能(或光能)？最多从中可获得多少电能(或光能)？

B3.让一个非自发过程实际发生，最少需要多少电能(或光能)？
