In chemical equilibrium the forward and reverse reaction rates are such that each chemical species is being created at the same rate it is being destroyed. In other words, the rate of the forward reaction is equal to the rate of the reverse reaction.

在化学平衡状态，正向和反向的反应速率是这样的情况：每一种化学物质都以同样的速率生成和消失。换句话说，正向反应的速率等于反向反应的速率。

Far from equilibrium, the forward and reverse reaction rates no longer balance and the concentration of reactants and products is no longer constant. For every forward reaction <math>\alpha </math> molecules of A are destroyed. For every reverse reaction <math>\alpha </math> molecules of A are created. In the case of an elementary reaction step the reaction order in each direction equals the molecularity, so that the rate of change in the number of moles of A is then

在远离平衡态时，正向和反向反应速率不再是平衡的，反应物和产物的浓度不再是恒定的。对于每一个前向反应，a 的分子会消失。对于每一个逆反应，a 的分子都会被产生出来。在基本反应步骤中，每个方向的反应级数等于“反应分子数”（molecularity），因此 a 的摩尔数的变化率就是
This system of equations has a single stable fixed point when the forward rates and the reverse rates are equal (when <math>{d \over dt}=0</math> for every species). This means that the system evolves to the equilibrium state, and this is the only state to which it evolves.

这个系统的方程组有一个单一的稳定不动点解，这个解的情况就是每个物种的正向速率和反向速率相等。这意味着这个系统是往平衡状态演化，而且这个平衡状态这是系统演化到的唯一状态。
