For the reaction of carbon with carbon dioxide to make carbon monoxide, one set of conditions produced a Kc = 1.6 × 10-1. At equilibrium at a certain temperature, the concentration of product was 0.80 M. What was the concentration of carbon dioxide at that temperature?
C(s) + CO2(g) ? 2CO(g)
- 4.0 M
- 0.80 M
- 6.4 M
- 0.64 M
- 5.0 M
