Solution Summary

The process is key to the sensitivity of photographic films. A detailed explanation is given.

Solution Preview

Bond eneregy = 255*10^3 joules/mol. The incoming photons must be able to supply this much amount of energy per mole to completely break the bonds.

This is for one mole; but ...
