Solution

The correct option is B Endothermic reaction
Endothermic reactions are those in which energy is absorbed. In the reaction of silver bromide, sunlight is absorbed and so, silver bromide decomposes into silver and bromine. This is a decomposition reaction, not a combination or displacement reaction.

$2 A g B r s u n l i g h t - ---- \to 2 A g + B r_{2}$

Q. What is the action of the silver acetate on ethyl bromide?

Q. Assertion :Silver bromide is used in photography. Reason: Silver bromide is used in photography because silver bromide is photosensitive. It decomposes and is converted into metallic silver grains when light is incident on it.

A photographic film is coated with a silver bromide layer. When light falls on this film, silver bromide molecules dissociate and the film records the light there. A minimum of 0.6 eV is needed to dissociate a silver bromide molecule. Find the maximum wavelength of light that can be recorded by the film.
