13.4 Exercise 19

Avg difficulty 2.5

Cobalt metal can be prepared by reducing cobalt(II) oxide with carbon monoxide.

CoO(s)+CO(g)⇌Co(s)+CO2(g)Kc=4.90×102at550°C\text{CoO} \left(s\right) + \text{CO} \left(g\right) \rightleftharpoons \text{Co} \left(s\right) + \text{CO}_{2} \left(g\right) K_{c} = 4.90 \times 10^{2} \text{at} 550 °\text{C}

What concentration of CO remains in an equilibrium mixture with [CO2] = 0.100 M?
