NHaHS(s) NH3(g) + H2S(g) Express the equilibrium constant to three significant figures An equilibrium miture of this reaction at s certain temperature was found to have INHs] 280 M and (H2SI 0.370 M You may want to referano Paces 051-853) Sedion 15 6 while completing this problem K. 0.0979 Subm?

Explanation / Answer

    NH4HS(s) -------------> NH3(g) + H2S(g)

Kc    = [NH3][H2S]

[NH3]   = 0.28M

[H2S]   = 0.37M

KC   = 0.28*0.37   = 0.1036
