The ratio of the rate of formation of a reaction product or rate of consumption of a reactant to the corresponding stoichiometric coefficient is called the chemical reaction rate. In the case of a homogeneous reaction occurring in a closed system of constant volume, the reaction rate ...
Chemical reaction rates are influenced by several factors. Temperature is one of the most important factors. As the temperature increases, the rate of a chemical reaction generally increases. This is because at higher temperatures, the molecules have more kinetic energy. They move faster and collide...
A. lowering the temperature. B. decreasing the concentration of reactants. C. adding a catalyst. D. reducing the pressure. 相关知识点: 试题来源: 解析 C。解析:添加催化剂可以提高化学反应的速率。选项 A 降低温度通常会使反应速率减慢。选项 B 降低反应物浓度也会使反应速率减慢。选项 D 降低压力对...
In general, a factor that increases the number of collisions between particles will increase the reaction rate and a factor that decreases the number of collisions between particles will decrease thechemical reactionrate. Concentration of Reactants ...
The rate of a chemical reaction refers to the speed with which reactants are converted to products, the substances formed from the reaction. Collision theory explains that chemical reactions occur at different rates by proposing that in order for a react

The chemical reaction rate was used to describe the influence of the environmental temperature on the adiabatic temperature rise of concrete, and the relationship between the chemical reaction rate and the curing temperature was discussed. 对不同养护温度下的混凝土绝热温升进行了研究,采用化学反应速率描述...
