When a mixture of ph3, p2, and h2 comes to equilibrium at 873 k according to the reaction
2ph3(g)←−→p2(g)+3h2(g)kp = 398 at 873 k,
where pp2 = 0.414 atm and ph2 = 0.827 atm .

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
