Photogray lenses incorporate small amounts of silver chloride in the glass of the lens. When light hits the AgCl particles, the following reaction occurs:

The silver metal formed causes the lenses to darken. The enthalpy change for this reaction is 3.10 × 102 kJ/ mol. Assuming that all this energy must be supplied by light, what is the maximum wavelength of light that can cause this reaction?
