补充资料：速率分布函数
分子式：
CAS号：

性质：任何宏观体系中大量分子的频繁碰撞，分子速率具有不同的值，处于热平衡状态中每个分子速率可变化，温度不变时体系中所有分子速率分布不会改变，麦克斯威首先导出了气体速率分布函数，常有三种形式：一维气体二维气体三维气体式中u,υ,ω为三个方向上的分子分速率。在化学动力学中推导硬球碰撞理论的速率公式中一般应用二维速率分布公式。  速率控制步骤  rate controlling step  又称决速步。在包含一系列反应步骤的连串反应中，如果有某个反应步骤其速率或速率常数之值远远小于其他反应步骤的值，即远比其他反应步骤在动力学上进行艰难，则称之为该连串反应的速率控制步骤。整体连串反应的速率将由速率控制步骤的速率来决定。
