The equation that represents the water-gas reaction is:
- A$CO_{(g)} + H_2O_{(g)} \xrightarrow[\text{catalyst}]{673 \ K} CO_{2(g)} + H_{2(g)}$
- B$CH_{4(g)} + H_2O_{(g)} \xrightarrow[Ni]{1270 \ K} CO_{(g)} + 3H_{2(g)}$
- C$C_{(s)} + H_2O_{(g)} \xrightarrow{1270 \ K} CO_{(g)} + H_{2(g)}$
- D$2C_{(s)} + O_{2(g)} + 4N_{2(g)} \xrightarrow{1273 \ K} 2CO_{(g)} + 4N_{2(g)}$
