Photogray lenses have small amounts of silver chloride in their glass. when light strikes the agcl particles the lenses darken due to the reaction: agcl → ag + cl. the enthalpy change for the reaction is 310 kj mol−1. if all this energy were to be supplied by light, what is the maximum wavelength of the light that can cause this reaction?

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
