Photogray lenses incorporate small amounts of silver chloride in the glass of the lens.The following reaction occurs in the light,causing the lenses to darken:
AgCl $\to$ Ag + Cl
The enthalpy change for this reaction is 3.10 $\times$ 10² kJ/mol.Assuming all this energy is supplied by light,what is the maximum wavelength of light that can cause this reaction?
