Question

Give the chemical equation for the production of water gas.

Answer 1

• Water-gas is a mixture of Carbon monoxide $\left(\mathrm{CO}\right)$ and hydrogen $\left({\mathrm{H}}_2\right)$.
• It is produced by passing steam over red-hot coke at $1270\mathrm{K}$.
• $\underset{\mathrm{Coke}}{\mathrm{C}\left(\mathrm{s}\right)}+\underset{\mathrm{Steam}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)}\stackrel{1270\mathrm{K}}{\to }\underset{\mathrm{Water}\mathrm{gas}}{\mathrm{CO}\left(\mathrm{g}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right)}$
