摘要

本文對恆溫恆容理想氣體化學反應物最適宜的比例進行了一般的討論，指出對於恆溫恆容理想氣體化學反應，如果Σvi = 0，反應物有最佳配比；如Σvi ≠ 0，反應物無最佳配比，除非n^0為常數、對於Σvi ≠ 0的反應，為了獲得較大的生成物的摩爾分數，反應物的初始摩爾分數仍應與它們的計量系數成比例，且如果Σvi ＜ 0, n^0應盡可能大，如果Σvi ＞ 0, n^0應盡可能小。

In thi s paper. author gives general discu ssion to the most suitable proportion of the reactant s of isothermal and isochoric react ions of ideal gases. It is pointed out that for isothermal and isochoric reactions of idea l gases. there is the most suitable proportion for the reactants if Σvi = 0 and there is no the most suitable proport ion for the reactant s if Σvi ≠ 0 except that n^0 is constant: for the reaction of Σvi ≠ 0. to gain , i bigger molar fra ctions of products, inita l molar fractions of reactants should be proportional to the ir stoichiometric cofficicnt and n^0 should be as big as possible if Σvi ＜ 0 and as small as possible if Σvi ＞ 0.
