Answer to Question #119144 in General Chemistry for Abigail Rouse

Question

Please pick the correct expression for the following equilibrium expression: FeO (s) + CO (g) <--> Fe (s) + CO₂ (g) *

[CO₂][Fe] / [FeO] [CO]
[FeO] [CO] / [CO₂][Fe]
[CO]/[CO₂]
[CO₂]/[CO]

Answer 1

Answer:

The equilibrium constant expression is the ratio of the concentrations of the products over the reactants. Each concentration of product or reactant is raised to the power of its coefficient. So

[CO₂]/[CO]

Fe and FeO are in solid state. Thus not taken into account.
