In a chemical reaction, what will slow down the reaction rate? A. Increase surface area B. Higher temperature C. Decrease the amount of reactants D. Add an inhibitor 相关知识点: 试题来源: 解析 D。增加反应物的表面积和升高温度会加快反应速率。减少反应物的量不一定会明显减慢反应速率。添加...
In a chemical reaction, if the pressure is increased, what will happen to the reaction rate? A. Decrease B. Remain unchanged C. Increase D. Depend on the reaction 相关知识点: 试题来源: 解析 C。解析:对于有气体参与的反应,增加压力通常会增加反应速率,因为压力增加会使气体分子间距离减小,碰撞...
A. The rate of a chemical reaction. B. The amount of reactants at equilibrium. C. The extent of a chemical reaction at equilibrium. D. The pressure of a reaction. 相关知识点: 试题来源: 解析 C。解析:平衡常数 K 是衡量化学反应在平衡状态下进行程度的量。A 选项是反应速率;B 选项是平衡...
What is the name of the substance that changes the rate of a chemical reaction without being consumed? A. Reactant B. Product C. Catalyst D. Solute 相关知识点: 试题来源: 解析 C。这里考查“catalyst”(催化剂)的概念,它能改变反应速率但自身不被消耗。选项 A“reactant”是反应物;选项 B“...
