影响化学反应速率的条件很多 ,但各种条件对反应速率影响的大小和方向 ,在文献中仅限于浓度、温度、压强和催化剂等。因此 ,我选择稀硫酸和稀硫代硫酸钠的反应 ,实验研究电场、磁场对化学反应的影响。本文较为详细地记载和介绍了无外加电场与磁场条件下和有外加电场与磁场条件下 ,稀硫酸(0 .1mol/L)和稀硫代硫酸钠 (0 .1mol/L)反应速率大小的测定过程、实验结论以及本人不成熟的认识。外加直流电场 ,可以加大Na2 S2 O3和H2 SO4 反应的反应速率 ,若外加交变电场 ,则反应速率更大 ;若外加磁场 ,则反应速率减小。
There are many conditions affecting the chemical reaction rate, but the size and direction of the influence of various conditions on the reaction rate are limited to the concentration, temperature, pressure, and catalyst in the literature. Therefore, I chose the reaction of dilute sulfuric acid and dilute sodium thiosulfate to study the effect of electric and magnetic fields on chemical reactions. This article describes and describes in detail the reaction rate of dilute sulfuric acid (0.1 mol/L) and dilute sodium thiosulfate (0.1 mol/L) under the conditions of external electric field and magnetic field without external electric field and magnetic field. Measurement process, experimental conclusions, and my immature understanding. External DC electric field can increase the reaction rate of Na2S2O3 and H2SO4 reaction. If an alternating electric field is applied, the reaction rate will be greater. If a magnetic field is applied, the reaction rate will decrease.
