HI离解常数的光谱测定

SPECTROMETRIC DETERMINATION OF DISSOCIATION CONSTANT OF HYDROGEN IODIDE

根据统计热力学原理自行设计了本实验并测定了ＨＩ在不同温度下的离解常数，得知ＨＩ的离解常数数值主要决定于ＨＴ及其高解产物的平动以及ＨＩ分子的转动．本法也可用于其他单、双原子分子参与的气相反应平衡常数的测定．

The dissociation constant of hydrogen iodide has been determined at different temperatures,based on the prin ciple of statistical thermodynamics. The experiments shouo that the dissociation constant value of hydrogen iodide depends on the flat movements of hydrogen iodide and its dissociating products and the rotation of the hydrogen iodide molecuses, the metted can be used for determination of equilibrum Canstants of other gaseous reactions in which the single or the double atom molecules participate.
