Sun glasses have small amount of AgCl incorporated in the lenses. When light of appropriate wavelength is exposed it turns to gray colour to reduce the glare following the reactions: AgClhv−→Ag (Gray)+12Cl2 If the heat of reaction for the decomposition of AgCl is 248 kJ mol−1. Find the wavelength needed to induce the desired process? |
