摘要
在均相反应中由于不可能有一种物质浓度可以降为零，可以建立平衡态，反应不可能进行到底。而对于有气相产生的复相反应，可以建立平街街态，但改变气相压力可以使反应进行到底。而对于没有气体产生复相（固体液体分别是纯态）反应则不可能建立平衡量态，化学反应能进行到底.
An equilibrium can be established in a hernogenous rcacition in which concentration of all species does not reduce to zero. A heterogeneous reaction that produce g3ses proceed to state of equilibrium.The reactants are complete trans formed into products whell pressure of gases is changed, and vice versa. An equilibrium can't be established in a heterogeneous reaction that does not produce gases.
