When it is exposed to sunlight, silver chloride breaks down into silver and chlorine. What is the correct equation for this decomposition reaction?

The correct equation for the decomposition reaction of Silver chloride :

2AgCl(s)⇒2Ag(s)+Cl₂(g)

Given

Silver chloride breaks down into Silver and Chlorine.

Required

The correct equation

Solution

Decomposition reaction : a single reactants breaks down into 2 or more products. The reaction is the reverse of synthesis reaction

General formula :

AB ⇒ A + B

So for decomposition of Silver chloride :

2AgCl(s)⇒2Ag(s)+Cl₂(g)
