[6] 5. A 1.50 L container made of inert material was filled with H2S(g) and excess solid tin.
The sealed container was heated to 1.200 X 10³ K, causing the pressure to rise to 12.0 atm. After
some time at this temperature the following equilibrium was established:
K
p
= 22.8 at 1.200 X 10³ K
Calculate the partial pressure for the H2(g) and calculate the mass of SnS formed at equilibrium.
Sn(s) + H2S(g)
SnS(s) + H2(g)
