Chemistry Class 11 NCERT Solutions Chapter 7 Equilibrium Part 8

Q: 22. Monochloride decomposes into bromine and chloride and reaches the equilibrium:

For which at 500 K. If initially pure is present at a concentration of , what is its molar concentration in the mixture at equilibrium?


Let the amount of bromine and chlorine formed at equilibrium be The given reaction is

Now, we can write,

Therefore, at equilibrium,
