Consider the equilibrium `Ni(s)+4CO(g)hArrNi(CO)_(4)(g), K_(p)=0.125at

1.	Consider the equilibrium `Ni(s)+4CO(g)hArrNi(CO)_(4)(g), K_(p)=0.125atm^(-3)` If equal number of moles of `CO "and" Ni(CO)_(4)` (ideal gases) are mixed in a small container fitted with a piston, find the maximum total pressure (in atm) to which this mixture must be brough in order to just precipitate out metallic `Ni`?
Answer» Correct Answer - 4 `Ni(s)+4CO(g)hArrNi(CO)_(4)(g)` `P P` For backward reaction `Q_(P)geK_(P)` `(P)/(P^(4))geK_(P)` `therefore (1)/(P^(3))ge0.125atm^(-3)` `P^(3)le8atm^(3)` `Ple2atm` `P_(t otal)=2P=4atm`.
