Question

The equilibrium constant for the following reaction is 1.6 ×10⁵ at 1024 K.

Find the equilibrium pressure of all gases if 10.0 bar of HBr is introduced into a sealed container at 1024 K.

Answer 1

Given,

for the reaction i.e.,

Therefore, for the reaction the equilibrium constant will be,

Now, let p be the pressure of both H₂ and Br₂ at equilibrium.

Now, we can write,

Therefore, at equilibrium,
