An equilibrium system is shown below.
H2O(g)+CO(g)⇌H2(g)+CO2(g) \text{H}_2\text{O}(\text{g}) + \text{CO}(\text{g}) \rightleftharpoons \text{H}_2(\text{g}) + \text{CO}_2(\text{g}) H2O(g)+CO(g)⇌H2(g)+CO2(g)Different amounts of H2O\text{H}_2\text{O}H2O, CO\text{CO}CO, H2\text{H}_2H2, and CO2\text{CO}_2CO2 are added to four identical containers of the same volume, as shown in the table below.
| Container | H2O / mol\text{H}_2\text{O} \text{ / mol}H2O / mol | CO / mol\text{CO} \text{ / mol}CO / mol | H2 / mol\text{H}_2 \text{ / mol}H2 / mol | CO2 / mol\text{CO}_2 \text{ / mol}CO2 / mol |
|---|---|---|---|---|
| A | 1 | 1 | 1 | 0 |
| B | 0 | 1 | 1 | 1 |
| C | 1 | 0 | 1 | 1 |
