Question
We could also write this reaction three other ways, listed below. The equilibrium constants for all of the reactions are related. Write the equilibrium constant for each new reaction in terms of K, the equilibrium constant for the reaction above.
Bromine reacts readily with hydrogen gas to make hydrogen bromide.
One way to represent this equilibrium is:
1/2 H2(g) + 1/2 Br2(g)HBr(g)
Explanation / Answer
For gases equilibrium constant is measured in terms of partial pressures.
K1=(PH2 x PBr2)/P2HBr
K2=P2HBr/(PH2 x PBr2)
K3=(PH2 x PBr2)1/2/PHBr
Equilibrium constant for the above reaction is
K=(PH2 x PBr2)1/2/PHBr
