Final answer:
The equilibrium constant for the reaction HCl(g) (1/2) H2(g) (1/2)Cl2 (g) can be represented as K' = K^(1/2).
Step-by-step explanation:
In this reaction, the stoichiometric coefficients of the given reaction are divided by 2, so the equilibrium constant is calculated as follows:
K' = K(1/2)
