Based on three-variable Oregonator model and activated complex theory of reaction rate, nonideal B-Z reaction model is proposed.

同时系统地介绍了非理想性对B-Z反应体系动力学行为及热力学性质的影响。

This model was finely fitted by theexperimental results and was used to calculate the activation area,which was 0.127 〓/mol with little dependence of subphasetemperature. The positive activation area indicate that there is anincrease in area when the activated complex is formed, increasingthe surface pressure should decrease the rate constant and that theactivated complex is unimolecular in nature.

在一系列实验曲线的基础上，我们提出测量的面积变化应该由聚合中分子结构变化引起的急剧的瞬时面积变化与随后的与此面积变化相反的弛豫过程两部分组成，并据此提出一种反应动力学模型，此模型与实验结果相当吻合，此模型用于处理聚合速率的紫外光强依赖性，得到聚合速率常数近似与光强成二次幂指数关系；此模型也被用于计算活化面积，发现活化面积为〓，几乎与温度无关。
