摘　　要：根据理想气体定律,设计一锌与硫酸反应的封闭实验体系,通过测定体系(单位时间内体系)压出液体速度的快慢,验证了在原电池状态下锌与稀硫酸反应速度较非原电池状态下反应速度快的结论,实验效果较为明显,并分析了反应温度、浓度、锌片和铜片的面积等对反应速度的影响。An closed system of reaction of Zn and H_2SO_4 is designed according to ideal gas law.The following conclusion has been drawn by determing the dropping rate of pressured liquid drop.The test result shows clearly that reaction rate of Zn and H_2SO_4,when composing of Zn-Cu cell, is faster.Influence factors on the reaction rate,temperature,concentration of reactants, Zn and Cu of area and etc are also analysed.
