化学反应速率是用来衡量化学反应进行的快慢程度的,通常用单位时间内反应物的浓度的减少或生成物浓度的增加来表示·有关化学反应速率的计算一般有下列几种考查方式·一、根据概念计算反应速率例1反应4A(s)+3B(g)=2C(g)+D(g),经2min B的浓度减少了0·6mol/L,对此反应速率的表示 The chemical reaction rate is used to measure the speed of the chemical reaction. It is usually expressed as the reduction of the reactant concentration per unit time or the increase of the product concentration. The calculation of the chemical reaction rate generally has the following methods of examination. Calculate the reaction rate according to the concept. Example 1 Reaction 4A(s)+3B(g)=2C(g)+D(g), reduce the concentration of 0·6 mol/L at 2 min B, and express the rate of this reaction
