Chapter 10, Problem 150AP

In the metallurgical process of refining nickel, the metal is first combined with carbon monoxide to form tetracarbonylnickel, which is a gas at $\text{43°C:}$

$\text{Ni(}s\text{) + 4CO(}g\text{)}\underset{}{\to }{\text{Ni(CO)}}_{\text{4}}(g)$

This reaction separates nickel from other solid impurities. (a) Starting with 86.4 g of Ni, calculate the pressure of $\text{Ni}{\left(\text{CO}\right)}_4$ in a container of volume 4.00 L. (Assume the preceding reaction goes to completion.) (b) At temperatures above $\text{43°C}$, the pressure of the gas is observed to increase much more rapidly than predicted by the ideal gas equation. Explain.
