The equilbrium constant for the water-gas shift reaction is 5.0 at 400 oC:

Question

CO(g) + H2O(g) ↔ CO2(g) + H2(g)

Determine Qc if the following amounts (in moles) of each component is placed in a 1.0 L container.

CO 0.51
H2O 0.24
CO2 0.66
H2 0.73

Answer 1

CO(g) + H2O(g) ↔ CO2(g) + H2(g)
Qc = (CO2)(H2)/(CO)(H2O)
The quantities given are in mols/L; therefore, substitute those into the Qc equation above and calculate Qc.
