The reversible interactions of dissolved CO(2) with H(2)O and OH(-) to form H(2)CO(3) and HCO(3)(-) in aqueous solution have been investigated using spectrophotometric stopped-flow measurements. The progress of the reactions was monitored via indicators coupled to the pH changes during the reactions. The study, involving global analysis of the complete data set, spanned the temperature range 6.6-42.8 degrees C and resulted in the evaluation of all rate and equilibrium constants as well as activation parameters for the kinetic data and the reaction enthalpies and entropies for the equilibrium constants.
采用分光光度法停流测量研究了溶解 CO2 与 H2O 和 OH- 之间的可逆相互作用，以形成水溶液中的 H2CO3 和 HCO3-。通过与反应过程中 pH 值变化相关联的指示剂来监测反应的进展。该研究涉及对整个数据集的全局分析，温度范围为 6.6-42.8 摄氏度，评估了所有动力学数据的速率和平衡常数以及活化参数，以及平衡常数的反应焓和熵。
