A vessel of 250 litre was filled with 0.01 mole of `Sb_2S_3` and 0.01 mole of `H_2` to altain the equilibrium at `440^@C` as:
`Sb_2S_3(s) + 3H_2(g) iff 2Sb(s) + 3H_2S(g)`
After equilibrium, the `H_2S` formed was analysed by dissolving it in water and treating with excess of `Pb^(2+)` to give 1.19 g of PbS as precipitate. What is the value of `K_c` at `440^@C` ?
