The value of K for the dissociation of HI will be 0.02

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

\frac{1}{2}H_2+\frac{1}{2}I_2\rightarrow HI

K=\frac{[HI]}{[H_2]^\frac{1}{2}\times [I_2]^\frac{1}{2}}

K=50

On reversing the reaction:

HI\rightarrow \frac{1}{2}H_2+\frac{1}{2}I_2

K'=\frac{[H_2]^\frac{1}{2}\times [I_2]^\frac{1}{2}}{HI]}

K'=\frac{1}{K}=\frac{1}{50}=0.02

Thus the value of K for the dissociation of HI will be 0.02
