ratereactionkineticsreactions动力学increases Kinetics: The Rates of Reactions – Chemical kinetics – studies the reaction rates and mechanisms 16.1 Factors Affecting the Reaction Rate • Chemical nature of the reactants – each reaction has its own characteristic rate • Concentration – the reaction...
To solve the problem, we need to determine how the rate of a reaction changes with an increase in temperature. The problem states that the rate of reaction doubles (increases by two times) for every 10°C rise in temperature. We are asked to find the new rate of reaction when the tempe...
The reaction rate increases when the temperature rises. In this sentence, “when” can be replaced by ___. A. as B. while C. after D. before 相关知识点: 试题来源: 解析 A。“when”和“as”在这里都可以表示“当……的时候”。“while”通常表示“在……期间”,强调动作的同时进行;“after...
解析 C。本题考查浓度对反应速率的影响。increases 表示增加,反应物浓度增加,反应速率通常会加快,speeds up 符合。slows down 表示减慢,与增加浓度的效果相反。stays the same 表示保持不变,不符合实际。becomes unstable 表示变得不稳定,与浓度增加和反应速率的关系不大。反馈 收藏 ...
