Observe the given figure and answer the question that follows:

State True (T) or False (F) for the following statements.
(i) It is a photodecomposition reaction.
(ii) Silver chloride turns grey in sunlight to form silver metal.
(iii) It is an exothermic reaction.
(iv) Silver bromide also behaves in the same way and used in black and white photography.

Options

A. `{:("(i)","(ii)","(iii)","(iv)"),(T,T,T,T):}`
B. `{:("(i)","(ii)","(iii)","(iv)"),(T,F,T,F):}`
C. `{:("(i)","(ii)","(iii)","(iv)"),(T,F,F,T):}`
D. `{:("(i)","(ii)","(iii)","(iv)"),(T,T,F,T):}`

Answer

D

Explanation

White silver chloride turns grey in sunlight due to the decomposition of silver chloride into silver and chlorine by light. It is an endothermic reaction.
`underset("Silver chloride")(2AgCl_((s))) overset("Sunlight")to underset("Silver (grey)")(2Ag_((s)))+underset("Chlorine")(Cl_(2(g)))`
`underset("Silver bromide")(2AgBr_((s))) overset("Sunlight")to underset("Silver")(2Ag_((s))) +underset("Bromine")(Br_(2(g)))`
