Answer #1

The given reaction is-

NH₄HS (s) <---> NH₃ (g) + H₂S (g)

The concentration at equilibrium are given as-

[NH₃]_eq = 0.278 M

[H₂S]_eq = 0.355 M

The equilibrium constant (K_c) at this temperature is given by,

K_c = [NH₃]_eq × [H₂S]_eq

=> K_c = 0.278 × 0.355 = 0.09869, upto 5 decimal places

The answer is K_c= 0.09869
