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., H_2(g) + Br_2(g) ↔ 2HBr_(g) is 1.6x10⁵ Therefore, for the reaction  2HBr_(g) ↔ H_2(g) + Br_2(g)   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,
