摘要
对于BrO-3-穿心莲-丙酮-Mn2+-H2SO4体系的化学振荡反应,测定了不同浓度,不同温度下,穿心莲的振荡反应行为,得到了不同温度、浓度下反应的诱导期,振荡周期,并由此计算出振荡∝c3.0786∝c2.7793反应的表观活化能及穿心莲的反应级数。并得到下列关系:100·exp-10405tinT;1tp,1∝c3.6650·exp-116900·exp-9847.1T。T;1tp。
The oscillation reaction in herba andrographitis-MnSO_4-H_2SO_4-KBrO_3-acetone system was studied using a potentiometric method. From the experimental results, the oscillating induction period and the oscillating period were obtained. The apparent activation energy and reaction order were calculated. The relations were obtained as follows:1t_(in)∝c^(3.0786)_0·exp-10405T;1t_(p,1)∝c^(2.7793)_0·exp-11690T;tt_(p,2)∝c^(3.6650)_0·exp-9847.1T.
