The following equilibrium was studied by analyzing the equilibrium mixture for the amount of H2S produced.

Sb2S3(solid)+3H2(gas)<=>2Sb(solid)+3H2S(solid)

A vessel whose volume is 2.5L is filled with 0.0100 mole of antimony(III)Sulfide, Sb2S3, and 0.0100 mole H2. After the mixture came to equilibrium in a closed vessel at 440Celcius, the gaseous mixture was removed and the H2S dissolved in water. Sufficient lead(II)ion was added to react completely with H2S to precipitate lead(II)Sulfide, PbS. If 1.029g of Pbs was obtained what is the value of K(eq) at 440Celcius

k(eq)=the equilibrium constant
