Question
Water gas, a mixture of carbon monoxide and hydrogen, is
produced by treating carbon (in the form of coke or coal) with
steam at high temperatures.
C(s) + H₂O(g) → CO(g) + H₂(g)
Not all of the carbon available is converted to water gas since
some is burned to provide the heat for the endothermic
reaction of carbon and water. What mass of carbon must be
burned (to CO2 gas) to provide the energy to convert 5.35 kg
of carbon to water gas?
AfH˚ (kJ/mol)
Compound
H₂O(g)
CO(g)
CO₂(g)
Mass of carbon =
-241.83
-110.525
-393.509
g
