Question

State the type of chemical reactions of the

$2\mathrm{AgBr}\left(\mathrm{s}\right)\stackrel{\mathrm{sunlight}}{\to }2\mathrm{Ag}\left(\mathrm{s}\right)+{\mathrm{Br}}_2\left(\mathrm{l}\right)$

Answer 1

• Photo decomposition is a chemical reaction in which a substance is broken down into simple substances by exposure to light (photons)
• Decomposition occurs with the absorption of energy, they can be in the form of heat, light, and electric current.
• Photography is based on the photochemical process
• $\underset{\mathrm{Bromide}}{\underset{\mathrm{Silver}}{2\mathrm{AgBr}\left(\mathrm{s}\right)}}\stackrel{\mathrm{sunlight}}{\to }\underset{\mathrm{Silver}}{2\mathrm{Ag}\left(\mathrm{s}\right)}+\underset{\mathrm{Bromine}}{{\mathrm{Br}}_2\left(\mathrm{l}\right)}$ is an example of a Photochemical Reaction
