✦ Synopsis

The reaction between (\mathrm{CuI}) and (\mathrm{HgClBr}) in the solid state has been studied by resistivity measurements, X-ray diffraction, and chemical analysis. The reaction occurs differently at different molar ratios. The kinetics of the reaction has been studied by a visual technique. The reaction follows the usual rate law, (X^{n}=k t). The (k) 's show the Arrhenius dependence. The activation energy, (43.30 \pm 0.53 \mathrm{~kJ} / \mathrm{mol}), calculated by least-squares fitting, suggests that the reaction is diffusion controlled and proceeds via vapor phase diffusion of (\mathrm{HgClBr}). 1993 Academic Press.
