Question

Give equation for the following :

steam is passed over red hot coke.

Answer 1

Reaction of steam and red hot coke:

• When steam is passed over red hot coke, it will lead to the formation of carbon monoxide and hydrogen gas.
• The mixture of carbon monoxide and hydrogen is known as water gas.
• The balanced chemical reaction can be represented as:

$\underset{\mathrm{Red}\mathrm{hot}\mathrm{coke}}{\mathrm{C}\left(\mathrm{s}\right)}+\underset{\mathrm{Steam}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)}\stackrel{1000°\mathrm{C}}{\to }\underset{\mathrm{Water}\mathrm{gas}}{\underbrace{[\underset{\mathrm{Carbon}\mathrm{monoxide}}{\mathrm{CO}\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}]}}$
