Question

A company desires to produce nickel from refining nickel oxide and sulfide ores. the first step of the process will produce a nickel carbonyl gas ni(co)4 by heating the ore. the second step is as follows: ni(co)4(
g. ni(s) + 4co(
g. how would you accelerate the production of ni? select all that apply. reduce the concentration of nico4 increase the concentration of nico4 withdraw co from the products as it is forming adding co to the reaction

Answer 1

Answer is: increase the concentration of NiCO₄ and withdraw CO from the products as it is forming.

Balanced chemical reaction: NiCO₄(g) ⇄ Ni(s) + 4CO(g).
According to Le Chatelier's Principle the position of equilibrium moves to counteract the change:
1) the position of equilibrium will move to the right, so that the concentration of nickel carbonyl gas decreases again and produce more nickel.
2)  the position of equilibrium will move to the right, if we decrease concentration of carbon monoxide, more nickel carbonyl gas will decompose and produce more nickel.
