化学反应速率是研究反应进行快慢的一个量,其所指的反应既可以是可逆的,也可以是不可逆的,通常用单位时间内反应物浓度的减少或生成物浓度的增加来表示,因此,某一物质A的化学反应速率的计算表达式为:v-(A)=Δc(A)Δt.要正确理解这一表达式的涵义,以下几点应予以注意:1.利用该表 The rate of chemical reaction is a measure of the speed at which the reaction progresses. The reaction it refers to can be either reversible or irreversible. It is usually expressed as a decrease in the concentration of the reactants per unit time or as the concentration of the product increases. The expression for the chemical reaction rate of a substance A is: v-(A)=Δc(A)Δt. To understand the meaning of this expression correctly, the following points should be noted: 1. Use the table
