系统组分数的确定

Determination of the Number of Components in a System

分析了组分数表达式中各个量的意义,并举例说明组分数的计算.讨论了化学平衡和反应进行到底2种情形对系统组分数的影响：化学平衡中生成物只有1相的,化学平衡考虑与否不会影响组分数;可进行到底的反应,在特定条件下可按照化学平衡来处理.最后总结了快速确定系统组分数的步骤.

Physical quantities in the equation of components were demonstrated and exampleswere given to illustrate the calculation of the number of components. The effects of chemical e-quilibrium and complete reaction to components in a system were also discussed, including thatchemical equilibrium would not affect the number of components if the products of a chemical e-quilibrium were same phase, and complete reactions could be treated as chemical equilibriumwithout consuming multiple reactants. Finally, the steps for determining the number of compo-nents oS a system were summarized.
